# Objective
Since BufferVec was first introduced, `bytemuck` has added additional
traits with fewer restrictions than `Pod`. Within BufferVec, we only
rely on the constraints of `bytemuck::cast_slice` to a `u8` slice, which
now only requires `T: NoUninit` which is a strict superset of `Pod`
types.
## Solution
Change out the `Pod` generic type constraint with `NoUninit`. Also
taking the opportunity to substitute `cast_slice` with
`must_cast_slice`, which avoids a runtime panic in place of a compile
time failure if `T` cannot be used.
---
## Changelog
Changed: `BufferVec` now supports working with types containing
`NoUninit` but not `Pod` members.
Changed: `BufferVec` will now fail to compile if used with a type that
cannot be safely read from. Most notably, this includes ZSTs, which
would previously always panic at runtime.
# Objective
See https://github.com/gfx-rs/wgpu/issues/5488 for context and
rationale.
## Solution
- Disables `wgpu::Features::RAY_QUERY` and
`wgpu::Features::RAY_TRACING_ACCELERATION_STRUCTURE` by default. They
must be explicitly opted into now.
---
## Changelog
- Disables `wgpu::Features::RAY_QUERY` and
`wgpu::Features::RAY_TRACING_ACCELERATION_STRUCTURE` by default. They
must be explicitly opted into now.
## Migration Guide
- If you need `wgpu::Features::RAY_QUERY` or
`wgpu::Features::RAY_TRACING_ACCELERATION_STRUCTURE`, enable them
explicitly using `WgpuSettings::features`
This commit makes the following optimizations:
## `MeshPipelineKey`/`BaseMeshPipelineKey` split
`MeshPipelineKey` has been split into `BaseMeshPipelineKey`, which lives
in `bevy_render` and `MeshPipelineKey`, which lives in `bevy_pbr`.
Conceptually, `BaseMeshPipelineKey` is a superclass of
`MeshPipelineKey`. For `BaseMeshPipelineKey`, the bits start at the
highest (most significant) bit and grow downward toward the lowest bit;
for `MeshPipelineKey`, the bits start at the lowest bit and grow upward
toward the highest bit. This prevents them from colliding.
The goal of this is to avoid having to reassemble bits of the pipeline
key for every mesh every frame. Instead, we can just use a bitwise or
operation to combine the pieces that make up a `MeshPipelineKey`.
## `specialize_slow`
Previously, all of `specialize()` was marked as `#[inline]`. This
bloated `queue_material_meshes` unnecessarily, as a large chunk of it
ended up being a slow path that was rarely hit. This commit refactors
the function to move the slow path to `specialize_slow()`.
Together, these two changes shave about 5% off `queue_material_meshes`:
## Migration Guide
- The `primitive_topology` field on `GpuMesh` is now an accessor method:
`GpuMesh::primitive_topology()`.
- For performance reasons, `MeshPipelineKey` has been split into
`BaseMeshPipelineKey`, which lives in `bevy_render`, and
`MeshPipelineKey`, which lives in `bevy_pbr`. These two should be
combined with bitwise-or to produce the final `MeshPipelineKey`.
# Objective
Related to #10572
Allow the `Annulus` primitive to be meshed.
## Solution
We introduce a `Meshable` structure, `AnnulusMeshBuilder`, which allows
the `Annulus` primitive to be meshed, leaving optional configuration of
the number of angular sudivisions to the user. Here is a picture of the
annulus's UV-mapping:
<img width="1440" alt="Screenshot 2024-03-26 at 10 39 48 AM"
src="https://github.com/bevyengine/bevy/assets/2975848/b170291d-cba7-441b-90ee-2ad6841eaedb">
Other features are essentially identical to the implementations for
`Circle`/`Ellipse`.
---
## Changelog
- Introduced `AnnulusMeshBuilder`
- Implemented `Meshable` for `Annulus` with `Output =
AnnulusMeshBuilder`
- Implemented `From<Annulus>` and `From<AnnulusMeshBuilder>` for `Mesh`
- Added `impl_reflect!` declaration for `Annulus` and `Triangle3d` in
`bevy_reflect`
---
## Discussion
### Design considerations
The only interesting wrinkle here is that the existing UV-mapping of
`Ellipse` (and hence of `Circle` and `RegularPolygon`) is non-radial
(it's skew-free, created by situating the mesh in a bounding rectangle),
so the UV-mapping of `Annulus` doesn't limit to that of `Circle` as its
inner radius tends to zero, for instance. I don't see this as a real
issue for `Annulus`, which should almost certainly have this kind of
UV-mapping, but I think we ought to at least consider allowing mesh
configuration for `Circle`/`Ellipse` that performs radial UV-mapping
instead. (In these cases in particular, it would be especially easy,
since we wouldn't need a different parameter set in the builder.)

# Objective
- There are several redundant imports in the tests and examples that are
not caught by CI because additional flags need to be passed.
## Solution
- Run `cargo check --workspace --tests` and `cargo check --workspace
--examples`, then fix all warnings.
- Add `test-check` to CI, which will be run in the check-compiles job.
This should catch future warnings for tests. Examples are already
checked, but I'm not yet sure why they weren't caught.
## Discussion
- Should the `--tests` and `--examples` flags be added to CI, so this is
caught in the future?
- If so, #12818 will need to be merged first. It was also a warning
raised by checking the examples, but I chose to split off into a
separate PR.

# Objective
There are currently 2 different warning messages that are logged when
resizing on Linux with Nvidia drivers (introduced in
70c69cdd51).
Fixes#12830
## Solution
Generalize both to say:
```Couldn't get swap chain texture. This often happens with the NVIDIA drivers on Linux. It can be safely ignored.```
# Objective
- Since #12453, `DeterministicRenderingConfig` doesn't do anything
## Solution
- Remove it
---
## Migration Guide
- Removed `DeterministicRenderingConfig`. There shouldn't be any z
fighting anymore in the rendering even without setting
`stable_sort_z_fighting`
# Objective
This is a necessary precursor to #9122 (this was split from that PR to
reduce the amount of code to review all at once).
Moving `!Send` resource ownership to `App` will make it unambiguously
`!Send`. `SubApp` must be `Send`, so it can't wrap `App`.
## Solution
Refactor `App` and `SubApp` to not have a recursive relationship. Since
`SubApp` no longer wraps `App`, once `!Send` resources are moved out of
`World` and into `App`, `SubApp` will become unambiguously `Send`.
There could be less code duplication between `App` and `SubApp`, but
that would break `App` method chaining.
## Changelog
- `SubApp` no longer wraps `App`.
- `App` fields are no longer publicly accessible.
- `App` can no longer be converted into a `SubApp`.
- Various methods now return references to a `SubApp` instead of an
`App`.
## Migration Guide
- To construct a sub-app, use `SubApp::new()`. `App` can no longer
convert into `SubApp`.
- If you implemented a trait for `App`, you may want to implement it for
`SubApp` as well.
- If you're accessing `app.world` directly, you now have to use
`app.world()` and `app.world_mut()`.
- `App::sub_app` now returns `&SubApp`.
- `App::sub_app_mut` now returns `&mut SubApp`.
- `App::get_sub_app` now returns `Option<&SubApp>.`
- `App::get_sub_app_mut` now returns `Option<&mut SubApp>.`
# Objective
Fix crashing on Linux with latest stable Nvidia 550 driver when
resizing. The crash happens at startup with some setups.
Fixes#12199
I think this would be nice to get into 0.13.1
## Solution
Ignore `wgpu::SurfaceError::Outdated` always on this platform+driver.
It looks like Nvidia considered the previous behaviour of not returning
this error a bug:
"Fixed a bug where vkAcquireNextImageKHR() was not returning
VK_ERROR_OUT_OF_DATE_KHR when it should with WSI X11 swapchains"
(https://www.nvidia.com/Download/driverResults.aspx/218826/en-us/)
What I gather from this is that the surface was outdated on previous
drivers too, but they just didn't report it as an error. So behaviour
shouldn't change.
In the issue conversation we experimented with calling `continue` when
this error happens, but I found that it results in some small issues
like bevy_egui scale not updating with the window sometimes. Just doing
nothing seems to work better.

# Objective
Speed up CPU-side rendering.
## Solution
Use `QueryIter::for_each` and `Mut::bypass_change_detection` to minimize
the total amount of data being written and allow autovectorization to
speed up iteration.
## Performance
Tested against the default `many_cubes`, this results in greater than
15x speed up: 281us -> 18.4us.
As `ViewVisibility::HIDDEN` just wraps false, this is likely just
degenerating into `memset(0)`s on the tables.
Today, we sort all entities added to all phases, even the phases that
don't strictly need sorting, such as the opaque and shadow phases. This
results in a performance loss because our `PhaseItem`s are rather large
in memory, so sorting is slow. Additionally, determining the boundaries
of batches is an O(n) process.
This commit makes Bevy instead applicable place phase items into *bins*
keyed by *bin keys*, which have the invariant that everything in the
same bin is potentially batchable. This makes determining batch
boundaries O(1), because everything in the same bin can be batched.
Instead of sorting each entity, we now sort only the bin keys. This
drops the sorting time to near-zero on workloads with few bins like
`many_cubes --no-frustum-culling`. Memory usage is improved too, with
batch boundaries and dynamic indices now implicit instead of explicit.
The improved memory usage results in a significant win even on
unbatchable workloads like `many_cubes --no-frustum-culling
--vary-material-data-per-instance`, presumably due to cache effects.
Not all phases can be binned; some, such as transparent and transmissive
phases, must still be sorted. To handle this, this commit splits
`PhaseItem` into `BinnedPhaseItem` and `SortedPhaseItem`. Most of the
logic that today deals with `PhaseItem`s has been moved to
`SortedPhaseItem`. `BinnedPhaseItem` has the new logic.
Frame time results (in ms/frame) are as follows:
| Benchmark | `binning` | `main` | Speedup |
| ------------------------ | --------- | ------- | ------- |
| `many_cubes -nfc -vpi` | 232.179 | 312.123 | 34.43% |
| `many_cubes -nfc` | 25.874 | 30.117 | 16.40% |
| `many_foxes` | 3.276 | 3.515 | 7.30% |
(`-nfc` is short for `--no-frustum-culling`; `-vpi` is short for
`--vary-per-instance`.)
---
## Changelog
### Changed
* Render phases have been split into binned and sorted phases. Binned
phases, such as the common opaque phase, achieve improved CPU
performance by avoiding the sorting step.
## Migration Guide
- `PhaseItem` has been split into `BinnedPhaseItem` and
`SortedPhaseItem`. If your code has custom `PhaseItem`s, you will need
to migrate them to one of these two types. `SortedPhaseItem` requires
the fewest code changes, but you may want to pick `BinnedPhaseItem` if
your phase doesn't require sorting, as that enables higher performance.
## Tracy graphs
`many-cubes --no-frustum-culling`, `main` branch:
<img width="1064" alt="Screenshot 2024-03-12 180037"

You can see that `batch_and_prepare_binned_render_phase` is a much
smaller fraction of the time. Zooming in on that function, with yellow
being this branch and red being `main`, we see:
<img width="1064" alt="Screenshot 2024-03-12 175832"
src="https://github.com/bevyengine/bevy/assets/157897/0dfc8d3f-49f4-496e-8825-a66e64d356d0">
The binning happens in `queue_material_meshes`. Again with yellow being
this branch and red being `main`:
<img width="1064" alt="Screenshot 2024-03-12 175755"
src="https://github.com/bevyengine/bevy/assets/157897/b9b20dc1-11c8-400c-a6cc-1c2e09c1bb96">
We can see that there is a small regression in `queue_material_meshes`
performance, but it's not nearly enough to outweigh the large gains in
`batch_and_prepare_binned_render_phase`.

# Objective
Fixes#12727. All parts that `PersistentGpuBuffer` interact with should
be 100% safe both on the CPU and the GPU: `Queue::write_buffer_with`
zeroes out the slice being written to and when uploading to the GPU, and
all slice writes are bounds checked on the CPU side.
## Solution
Make `PersistentGpuBufferable` a safe trait. Enforce it's correct
implementation via assertions. Re-enable `forbid(unsafe_code)` on
`bevy_pbr`.
# Objective
- Closes https://github.com/bevyengine/bevy/pull/12415

- Refactored code that was changed/deprecated in `image` 0.25.
- Please review this PR carefully since I'm just making the changes

# Objective
Resolves#3824. `unsafe` code should be the exception, not the norm in
Rust. It's obviously needed for various use cases as it's interfacing
with platforms and essentially running the borrow checker at runtime in
the ECS, but the touted benefits of Bevy is that we are able to heavily
leverage Rust's safety, and we should be holding ourselves accountable
to that by minimizing our unsafe footprint.
## Solution
Deny `unsafe_code` workspace wide. Add explicit exceptions for the
following crates, and forbid it in almost all of the others.
* bevy_ecs - Obvious given how much unsafe is needed to achieve
performant results
* bevy_ptr - Works with raw pointers, even more low level than bevy_ecs.
* bevy_render - due to needing to integrate with wgpu
* bevy_window - due to needing to integrate with raw_window_handle
* bevy_utils - Several unsafe utilities used by bevy_ecs. Ideally moved
into bevy_ecs instead of made publicly usable.
* bevy_reflect - Required for the unsafe type casting it's doing.
* bevy_transform - for the parallel transform propagation
* bevy_gizmos - For the SystemParam impls it has.
* bevy_assets - To support reflection. Might not be required, not 100%
sure yet.
* bevy_mikktspace - due to being a conversion from a C library. Pending
safe rewrite.
* bevy_dynamic_plugin - Inherently unsafe due to the dynamic loading
nature.
Several uses of unsafe were rewritten, as they did not need to be using
them:
* bevy_text - a case of `Option::unchecked` could be rewritten as a
normal for loop and match instead of an iterator.
* bevy_color - the Pod/Zeroable implementations were replaceable with
bytemuck's derive macros.
# Objective
CI is currently broken because of `DiagnosticsRecorder` not being Send
and Sync as required by Resource.
## Solution
Wrap `DiagnosticsRecorder` internally with a `WgpuWrapper`.
# Objective
This gets Bevy building on Wasm when the `atomics` flag is enabled. This
does not yet multithread Bevy itself, but it allows Bevy users to use a
crate like `wasm_thread` to spawn their own threads and manually
parallelize work. This is a first step towards resolving #4078 . Also
fixes#9304.
This provides a foothold so that Bevy contributors can begin to think
about multithreaded Wasm's constraints and Bevy can work towards changes
to get the engine itself multithreaded.
Some flags need to be set on the Rust compiler when compiling for Wasm
multithreading. Here's what my build script looks like, with the correct
flags set, to test out Bevy examples on web:
```bash
set -e
RUSTFLAGS='-C target-feature=+atomics,+bulk-memory,+mutable-globals' \
cargo build --example breakout --target wasm32-unknown-unknown -Z build-std=std,panic_abort --release
wasm-bindgen --out-name wasm_example \
--out-dir examples/wasm/target \
--target web target/wasm32-unknown-unknown/release/examples/breakout.wasm
devserver --header Cross-Origin-Opener-Policy='same-origin' --header Cross-Origin-Embedder-Policy='require-corp' --path examples/wasm
```
A few notes:
1. `cpal` crashes immediately when the `atomics` flag is set. That is
patched in https://github.com/RustAudio/cpal/pull/837, but not yet in
the latest crates.io release.
That can be temporarily worked around by patching Cpal like so:
```toml
[patch.crates-io]
cpal = { git = "https://github.com/RustAudio/cpal" }
```
2. When testing out `wasm_thread` you need to enable the `es_modules`
feature.
## Solution
The largest obstacle to compiling Bevy with `atomics` on web is that
`wgpu` types are _not_ Send and Sync. Longer term Bevy will need an
approach to handle that, but in the near term Bevy is already configured
to be single-threaded on web.
Therefor it is enough to wrap `wgpu` types in a
`send_wrapper::SendWrapper` that _is_ Send / Sync, but panics if
accessed off the `wgpu` thread.
---
## Changelog
- `wgpu` types that are not `Send` are wrapped in
`send_wrapper::SendWrapper` on Wasm + 'atomics'
- CommandBuffers are not generated in parallel on Wasm + 'atomics'
## Questions
- Bevy should probably add CI checks to make sure this doesn't regress.
Should that go in this PR or a separate PR? **Edit:** Added checks to
build Wasm with atomics

# Objective
Currently the built docs only shows the logo and favicon for the top
level `bevy` crate. This makes views like
https://docs.rs/bevy_ecs/latest/bevy_ecs/ look potentially unrelated to
the project at first glance.
## Solution
Reproduce the docs attributes for every crate that Bevy publishes.
Ideally this would be done with some workspace level Cargo.toml control,
but AFAICT, such support does not exist.
# Objective
- Add serialize feature to bevy_color
- "Fixes #12527".
## Solution
- Added feature for serialization

## Changelog
- Serde serialization is now optional, with flag 'serialize'
## Migration Guide
- If user wants color data structures to be serializable, then
application needs to be build with flag 'serialize'
# Objective
* Adopted #12025 to fix merge conflicts
* In some cases we used manual impls for certain types, though they are
(at least, now) unnecessary.
## Solution
* Use macros and reflecting-by-value to avoid this clutter.
* Though there were linker issues with Reflect and the CowArc in
AssetPath (see https://github.com/bevyengine/bevy/issues/9747), I
checked these are resolved by using #[reflect_value].

# Objective
Simplify implementing some asset traits without Box::pin(async move{})
shenanigans.
Fixes (in part) https://github.com/bevyengine/bevy/issues/11308
## Solution
Use async-fn in traits when possible in all traits. Traits with return
position impl trait are not object safe however, and as AssetReader and
AssetWriter are both used with dynamic dispatch, you need a Boxed
version of these futures anyway.
In the future, Rust is [adding
](https://blog.rust-lang.org/2023/12/21/async-fn-rpit-in-traits.html)proc
macros to generate these traits automatically, and at some point in the
future dyn traits should 'just work'. Until then.... this seemed liked
the right approach given more ErasedXXX already exist, but, no clue if
there's plans here! Especially since these are public now, it's a bit of
an unfortunate API, and means this is a breaking change.
In theory this saves some performance when these traits are used with
static dispatch, but, seems like most code paths go through dynamic
dispatch, which boxes anyway.
I also suspect a bunch of the lifetime annotations on these function
could be simplified now as the BoxedFuture was often the only thing
returned which needed a lifetime annotation, but I'm not touching that
for now as traits + lifetimes can be so tricky.
This is a revival of
[pull/11362](https://github.com/bevyengine/bevy/pull/11362) after a
spectacular merge f*ckup, with updates to the latest Bevy. Just to recap
some discussion:
- Overall this seems like a win for code quality, especially when
implementing these traits, but a loss for having to deal with ErasedXXX
variants.
- `ConditionalSend` was the preferred name for the trait that might be
Send, to deal with wasm platforms.
- When reviewing be sure to disable whitespace difference, as that's 95%
of the PR.
## Changelog
- AssetReader, AssetWriter, AssetLoader, AssetSaver and Process now use
async-fn in traits rather than boxed futures.
## Migration Guide
- Custom implementations of AssetReader, AssetWriter, AssetLoader,
AssetSaver and Process should switch to async fn rather than returning a
bevy_utils::BoxedFuture.
- Simultaniously, to use dynamic dispatch on these traits you should
instead use dyn ErasedXXX.
# Objective
prevent gpu buffer allocations when running `as_bind_group` for assets
with texture dependencies that are not yet available.
## Solution
reorder the binding creation so that fallible items are created first.
# Objective
It's useful to have access to render pipeline statistics, since they
provide more information than FPS alone. For example, the number of
drawn triangles can be used to debug culling and LODs. The number of
fragment shader invocations can provide a more stable alternative metric
than GPU elapsed time.
See also: Render node GPU timing overlay #8067, which doesn't provide
pipeline statistics, but adds a nice overlay.
## Solution
Add `RenderDiagnosticsPlugin`, which enables collecting pipeline
statistics and CPU & GPU timings.

## Changelog
- Add `RenderDiagnosticsPlugin`
- Add `RenderContext::diagnostic_recorder` method

Full backtraces (`RUST_BACKTRACE=full`) are unchanged.
## Alternative solutions
Write a custom panic hook. This could potentially let use exclude a few
more callstack frames but requires a dependency on `backtrace` and is
incompatible with user-provided panic hooks.

# Objective
Fix missing `TextBundle` (and many others) which are present in the main
crate as default features but optional in the sub-crate. See:
- https://docs.rs/bevy/0.13.0/bevy/ui/node_bundles/index.html
- https://docs.rs/bevy_ui/0.13.0/bevy_ui/node_bundles/index.html
~~There are probably other instances in other crates that I could track
down, but maybe "all-features = true" should be used by default in all
sub-crates? Not sure.~~ (There were many.) I only noticed this because
rust-analyzer's "open docs" features takes me to the sub-crate, not the
main one.
## Solution
Add "all-features = true" to docs.rs metadata for crates that use
features.
## Changelog
### Changed
- Unified features documented on docs.rs between main crate and
sub-crates
# Objective
- Fix#12356
- better isolation of ci testing tools in dev tools instead of being in
various crates
## Solution
- Move the parts doing the work of ci testing to the dev tools
# Objective
Make bevy_utils less of a compilation bottleneck. Tackle #11478.
## Solution
* Move all of the directly reexported dependencies and move them to
where they're actually used.
* Remove the UUID utilities that have gone unused since `TypePath` took
over for `TypeUuid`.
* There was also a extraneous bytemuck dependency on `bevy_core` that
has not been used for a long time (since `encase` became the primary way
to prepare GPU buffers).
* Remove the `all_tuples` macro reexport from bevy_ecs since it's
accessible from `bevy_utils`.
---
## Changelog
Removed: Many of the reexports from bevy_utils (petgraph, uuid, nonmax,
smallvec, and thiserror).
Removed: bevy_core's reexports of bytemuck.
## Migration Guide
bevy_utils' reexports of petgraph, uuid, nonmax, smallvec, and thiserror
have been removed.
bevy_core' reexports of bytemuck's types has been removed.
Add them as dependencies in your own crate instead.
# Objective
Fixes#12353
When only `webp` was selected, `ImageLoader` would not be initialized.
That is, users using `default-features = false` would need to add `png`
or `bmp` or something in addition to `webp` in order to use `webp`.
This was also the case for `pnm`.
## Solution
Add `webp` and `pnm` to the list of features that trigger the
initialization of `ImageLoader`.
# Objective
- Resolves#11309
## Solution
- Add `bevy_dev_tools` crate as a default feature.
- Add `DevToolsPlugin` and add it to an app if the `bevy_dev_tools`
feature is enabled.
`bevy_dev_tools` is reserved by @alice-i-cecile, should we wait until it
gets transferred to cart before merging?

# Objective
Fix#12304. Remove unnecessary type registrations thanks to #4154.
## Solution
Conservatively remove type registrations. Keeping the top level
components, resources, and events, but dropping everything else that is
a type of a member of those types.
# Objective
Resolves#4154
Currently, registration must all be done manually:
```rust
#[derive(Reflect)]
struct Foo(Bar);
#[derive(Reflect)]
struct Bar(Baz);
#[derive(Reflect)]
struct Baz(usize);
fn main() {
// ...
app
.register_type::<Foo>()
.register_type::<Bar>()
.register_type::<Baz>()
// .register_type::<usize>() <- This one is handled by Bevy, thankfully
// ...
}
```
This can grow really quickly and become very annoying to add, remove,
and update as types change. It would be great if we could help reduce
the number of types that a user must manually implement themselves.
## Solution
As suggested in #4154, this PR adds automatic recursive registration.
Essentially, when a type is registered, it may now also choose to
register additional types along with it using the new
`GetTypeRegistration::register_type_dependencies` trait method.
The `Reflect` derive macro now automatically does this for all fields in
structs, tuple structs, struct variants, and tuple variants. This is
also done for tuples, arrays, `Vec<T>`, `HashMap<K, V>`, and
`Option<T>`.
This allows us to simplify the code above like:
```rust
#[derive(Reflect)]
struct Foo(Bar);
#[derive(Reflect)]
struct Bar(Baz);
#[derive(Reflect)]
struct Baz(usize);
fn main() {
// ...
app.register_type::<Foo>()
// ...
}
```
This automatic registration only occurs if the type has not yet been
registered. If it has been registered, we simply skip it and move to the
next one. This reduces the cost of registration and prevents overwriting
customized registrations.
## Considerations
While this does improve ergonomics on one front, it's important to look
at some of the arguments against adopting a PR like this.
#### Generic Bounds
~~Since we need to be able to register the fields individually, we need
those fields to implement `GetTypeRegistration`. This forces users to
then add this trait as a bound on their generic arguments. This
annoyance could be relieved with something like #5772.~~
This is no longer a major issue as the `Reflect` derive now adds the
`GetTypeRegistration` bound by default. This should technically be okay,
since we already add the `Reflect` bound.
However, this can also be considered a breaking change for manual
implementations that left out a `GetTypeRegistration` impl ~~or for
items that contain dynamic types (e.g. `DynamicStruct`) since those also
do not implement `GetTypeRegistration`~~.
#### Registration Assumptions
By automatically registering fields, users might inadvertently be
relying on certain types to be automatically registered. If `Foo`
auto-registers `Bar`, but `Foo` is later removed from the code, then
anywhere that previously used or relied on `Bar`'s registration would
now fail.
---
## Changelog
- Added recursive type registration to structs, tuple structs, struct
variants, tuple variants, tuples, arrays, `Vec<T>`, `HashMap<K, V>`, and
`Option<T>`
- Added a new trait in the hidden `bevy_reflect::__macro_exports` module
called `RegisterForReflection`
- Added `GetTypeRegistration` impl for
`bevy_render::render_asset::RenderAssetUsages`
## Migration Guide
All types that derive `Reflect` will now automatically add
`GetTypeRegistration` as a bound on all (unignored) fields. This means
that all reflected fields will need to also implement
`GetTypeRegistration`.
If all fields **derive** `Reflect` or are implemented in `bevy_reflect`,
this should not cause any issues. However, manual implementations of
`Reflect` that excluded a `GetTypeRegistration` impl for their type will
need to add one.
```rust
#[derive(Reflect)]
struct Foo<T: FromReflect> {
data: MyCustomType<T>
}
// OLD
impl<T: FromReflect> Reflect for MyCustomType<T> {/* ... */}
// NEW
impl<T: FromReflect + GetTypeRegistration> Reflect for MyCustomType<T> {/* ... */}
impl<T: FromReflect + GetTypeRegistration> GetTypeRegistration for MyCustomType<T> {/* ... */}

# Objective
Fixes#11298. Make the use of bevy_log vs bevy_utils::tracing more
consistent.
## Solution
Replace all uses of bevy_log's logging macros with the reexport from
bevy_utils. Remove bevy_log as a dependency where it's no longer needed
anymore.
Ideally we should just be using tracing directly, but given that all of
these crates are already using bevy_utils, this likely isn't that great
of a loss right now.
# Objective
While mucking around with batch_and_prepare systems, it became apparent
that `GpuArrayBufferIndex::index` doesn't need to be a NonMaxU32.
## Solution
Replace it with a normal u32.
This likely has some potential perf benefit by avoiding panics and the
NOT operations, but I haven't been able to find any substantial gains,
so this is primarily for code quality.
---
## Changelog
Changed: `GpuArrayBufferIndex::index` is now a u32.
## Migration Guide
`GpuArrayBuferIndex::index` is now a u32 instead of a `NonMaxU32`.
Remove any calls to `NonMaxU32::get` on the member.
# Objective
This PR unpins `web-sys` so that unrelated projects that have
`bevy_render` in their workspace can finally update their `web-sys`.
More details in and fixes#12246.
## Solution
* Update `wgpu` from 0.19.1 to 0.19.3.
* Remove the `web-sys` pin.
* Update docs and wasm helper to remove the now-stale
`--cfg=web_sys_unstable_apis` Rust flag.
---
## Changelog
Updated `wgpu` to v0.19.3 and removed `web-sys` pin.
This is an implementation within `bevy_window::window` that fixes
#12229.
# Objective
Fixes#12229, allow users to retrieve the window's size and physical
size as Vectors without having to manually construct them using
`height()` and `width()` or `physical_height()` and `physical_width()`
## Solution
As suggested in #12229, created two public functions within `window`:
`size() -> Vec` and `physical_size() -> UVec` that return the needed
Vectors ready-to-go.
### Discussion
My first FOSS PRQ ever, so bear with me a bit. I'm new to this.
- I replaced instances of ```Vec2::new(window.width(),
window.height());``` or `UVec2::new(window.physical_width(),
window.physical_height());` within bevy examples be replaced with their
`size()`/`physical_size()` counterparts?
- Discussion within #12229 still holds: should these also be added to
WindowResolution?
Although we cached hashes of `MeshVertexBufferLayout`, we were paying
the cost of `PartialEq` on `InnerMeshVertexBufferLayout` for every
entity, every frame. This patch changes that logic to place
`MeshVertexBufferLayout`s in `Arc`s so that they can be compared and
hashed by pointer. This results in a 28% speedup in the
`queue_material_meshes` phase of `many_cubes`, with frustum culling
disabled.
Additionally, this patch contains two minor changes:
1. This commit flattens the specialized mesh pipeline cache to one level
of hash tables instead of two. This saves a hash lookup.
2. The example `many_cubes` has been given a `--no-frustum-culling`
flag, to aid in benchmarking.

## Migration guide
* Duplicate `MeshVertexBufferLayout`s are now combined into a single
object, `MeshVertexBufferLayoutRef`, which contains an
atomically-reference-counted pointer to the layout. Code that was using
`MeshVertexBufferLayout` may need to be updated to use
`MeshVertexBufferLayoutRef` instead.
# Objective
- As part of the migration process we need to a) see the end effect of
the migration on user ergonomics b) check for serious perf regressions
c) actually migrate the code
- To accomplish this, I'm going to attempt to migrate all of the
remaining user-facing usages of `LegacyColor` in one PR, being careful
to keep a clean commit history.
- Fixes#12056.
## Solution
I've chosen to use the polymorphic `Color` type as our standard
user-facing API.
- [x] Migrate `bevy_gizmos`.
- [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs
- [x] Migrate sprites
- [x] Migrate UI
- [x] Migrate `ColorMaterial`
- [x] Migrate `MaterialMesh2D`
- [x] Migrate fog
- [x] Migrate lights
- [x] Migrate StandardMaterial
- [x] Migrate wireframes
- [x] Migrate clear color
- [x] Migrate text
- [x] Migrate gltf loader
- [x] Register color types for reflection
- [x] Remove `LegacyColor`
- [x] Make sure CI passes
Incidental improvements to ease migration:
- added `Color::srgba_u8`, `Color::srgba_from_array` and friends
- added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the
`Alpha` trait
- add and immediately deprecate (lol) `Color::rgb` and friends in favor
of more explicit and consistent `Color::srgb`
- standardized on white and black for most example text colors
- added vector field traits to `LinearRgba`: ~~`Add`, `Sub`,
`AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications
and divisions do not scale alpha. `Add` and `Sub` have been cut from
this PR.
- added `LinearRgba` and `Srgba` `RED/GREEN/BLUE`
- added `LinearRgba_to_f32_array` and `LinearRgba::to_u32`
## Migration Guide
Bevy's color types have changed! Wherever you used a
`bevy::render::Color`, a `bevy::color::Color` is used instead.
These are quite similar! Both are enums storing a color in a specific
color space (or to be more precise, using a specific color model).
However, each of the different color models now has its own type.
TODO...
- `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`,
`Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`,
`Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`.
- `Color::set_a` and `Color::a` is now `Color::set_alpha` and
`Color::alpha`. These are part of the `Alpha` trait in `bevy_color`.
- `Color::is_fully_transparent` is now part of the `Alpha` trait in
`bevy_color`
- `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for
`g`, `b` `h`, `s` and `l` have been removed due to causing silent
relatively expensive conversions. Convert your `Color` into the desired
color space, perform your operations there, and then convert it back
into a polymorphic `Color` enum.
- `Color::hex` is now `Srgba::hex`. Call `.into` or construct a
`Color::Srgba` variant manually to convert it.
- `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`,
`ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now
store a `LinearRgba`, rather than a polymorphic `Color`
- `Color::rgb_linear` and `Color::rgba_linear` are now
`Color::linear_rgb` and `Color::linear_rgba`
- The various CSS color constants are no longer stored directly on
`Color`. Instead, they're defined in the `Srgba` color space, and
accessed via `bevy::color::palettes::css`. Call `.into()` on them to
convert them into a `Color` for quick debugging use, and consider using
the much prettier `tailwind` palette for prototyping.
- The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with
the standard naming.
- Vector field arithmetic operations on `Color` (add, subtract, multiply
and divide by a f32) have been removed. Instead, convert your colors
into `LinearRgba` space, and perform your operations explicitly there.
This is particularly relevant when working with emissive or HDR colors,
whose color channel values are routinely outside of the ordinary 0 to 1
range.
- `Color::as_linear_rgba_f32` has been removed. Call
`LinearRgba::to_f32_array` instead, converting if needed.
- `Color::as_linear_rgba_u32` has been removed. Call
`LinearRgba::to_u32` instead, converting if needed.
- Several other color conversion methods to transform LCH or HSL colors
into float arrays or `Vec` types have been removed. Please reimplement
these externally or open a PR to re-add them if you found them
particularly useful.
- Various methods on `Color` such as `rgb` or `hsl` to convert the color
into a specific color space have been removed. Convert into
`LinearRgba`, then to the color space of your choice.
- Various implicitly-converting color value methods on `Color` such as
`r`, `g`, `b` or `h` have been removed. Please convert it into the color
space of your choice, then check these properties.
- `Color` no longer implements `AsBindGroup`. Store a `LinearRgba`
internally instead to avoid conversion costs.

# Objective
- Cull 2D text outside the view frustum.
- Part of #11081.
## Solution
- Compute AABBs for entities with a `Text2DBundle` to enable culling
them.
`text2d` example with AABB gizmos on the text entities:
https://github.com/bevyengine/bevy/assets/18357657/52ed3ddc-2274-4480-835b-a7cf23338931
---
## Changelog
### Added
- 2D text outside the view are now culled with the
`calculate_bounds_text2d` system adding the necessary AABBs.
# Objective
Split up from #12017, rename Bevy's direction types.
Currently, Bevy has the `Direction2d`, `Direction3d`, and `Direction3dA`
types, which provide a type-level guarantee that their contained vectors
remain normalized. They can be very useful for a lot of APIs for safety,
explicitness, and in some cases performance, as they can sometimes avoid
unnecessary normalizations.
However, many consider them to be inconvenient to use, and opt for
standard vector types like `Vec3` because of this. One reason is that
the direction type names are a bit long and can be annoying to write (of
course you can use autocomplete, but just typing `Vec3` is still nicer),
and in some intances, the extra characters can make formatting worse.
The naming is also inconsistent with Glam's shorter type names, and
results in names like `Direction3dA`, which (in my opinion) are
difficult to read and even a bit ugly.
This PR proposes renaming the types to `Dir2`, `Dir3`, and `Dir3A`.
These names are nice and easy to write, consistent with Glam, and work
well for variants like the SIMD aligned `Dir3A`. As a bonus, it can also
result in nicer formatting in a lot of cases, which can be seen from the
diff of this PR.
Some examples of what it looks like: (copied from #12017)
```rust
// Before
let ray_cast = RayCast2d::new(Vec2::ZERO, Direction2d::X, 5.0);
// After
let ray_cast = RayCast2d::new(Vec2::ZERO, Dir2::X, 5.0);
```
```rust
// Before (an example using Bevy XPBD)
let hit = spatial_query.cast_ray(
Vec3::ZERO,
Direction3d::X,
f32::MAX,
true,
SpatialQueryFilter::default(),
);
// After
let hit = spatial_query.cast_ray(
Vec3::ZERO,
Dir3::X,
f32::MAX,
true,
SpatialQueryFilter::default(),
);
```
```rust
// Before
self.circle(
Vec3::new(0.0, -2.0, 0.0),
Direction3d::Y,
5.0,
Color::TURQUOISE,
);
// After (formatting is collapsed in this case)
self.circle(Vec3::new(0.0, -2.0, 0.0), Dir3::Y, 5.0, Color::TURQUOISE);
```
## Solution
Rename `Direction2d`, `Direction3d`, and `Direction3dA` to `Dir2`,
`Dir3`, and `Dir3A`.
---
## Migration Guide
The `Direction2d` and `Direction3d` types have been renamed to `Dir2`
and `Dir3`.
## Additional Context
This has been brought up on the Discord a few times, and we had a small
[poll](https://discord.com/channels/691052431525675048/1203087353850364004/1212465038711984158)
on this. `Dir2`/`Dir3`/`Dir3A` was quite unanimously chosen as the best
option, but of course it was a very small poll and inconclusive, so
other opinions are certainly welcome too.

# Objective
- Complete compatibility with CSS Module 4
## Solution
- Added `Oklcha` which implements the Oklch color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Oklcha` to `Oklaba` using the provided `From` implementations
and then handle accordingly.
## Notes
This is the _last_ color space missing from the CSS Module 4 standard,
and is also the one I believe we should recommend users actually work
with for hand-crafting colours. It has all the uniformity benefits of
Oklab combined with the intuition chroma and hue provide (when compared
to a-axis and b-axis parameters).
# Objective
- Improve compatibility with CSS Module 4
- Simplify `Lcha` conversion functions
## Solution
- Added `Laba` which implements the Lab color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Laba` to either `Xyza` or `Lcha` using the provided `From`
implementations and then handle accordingly.
## Notes
The Lab color space is a required stepping stone when converting between
XYZ and Lch, therefore we already use the Lab color model, just in an
nameless fashion prone to errors.
This PR also includes a slightly broader refactor of the `From`
implementations between the various colour spaces to better reflect the
graph of definitions. My goal was to keep domain specific knowledge of
each colour space contained to their respective files (e.g., the
`From<Oklaba> for LinearRgba` definition was in `linear_rgba.rs` when it
probably belongs in `oklaba.rs`, since Linear sRGB is a fundamental
space and Oklab is defined in its relation to it)
# Objective
- Make these types usable in reflection-based workflows.
## Solution
- The usual. Also reflect `Default` and `Component` behaviors so that
the types can be constructed, inserted, and removed.
# Objective
Memory usage optimisation
## Solution
`HashMap` and `HashSet`'s keys are immutable. So using mutable types
like `String`, `Vec<T>`, or `PathBuf` as a key is a waste of memory:
they have an extra `usize` for their capacity and may have spare
capacity.
This PR replaces these types by their immutable equivalents `Box<str>`,
`Box<[T]>`, and `Box<Path>`.
For more context, I recommend watching the [Use Arc Instead of
Vec](https://www.youtube.com/watch?v=A4cKi7PTJSs) video.

# Objective
`CameraProjectionPlugin<T>`'s bounds are `T: CameraProjection`. But the
bounds for `CameraProjectionPlugin` implementing `Plugin` are `T:
CameraProjection + Component + GetTypeRegistration`. This means that if
`T` is valid for `CameraProjectionPlugin`'s bounds, but not the plugin
implementation's bounds, then `CameraProjectionPlugin` would not
implement `Plugin`. Which is weird because you'd expect a struct with
`Plugin` in the name to implement `Plugin`.
## Solution
Make `CameraProjectionPlugin<T>`'s bounds `T: CameraProjection +
Component + GetTypeRegistration`. I also rearranged some of the code.
---
## Changelog
- Changed `CameraProjectionPlugin<T>`'s bounds to `T: CameraProjection +
Component + GetTypeRegistration`
## Migration Guide
`CameraProjectionPlugin<T>`'s trait bounds now require `T` to implement
`CameraProjection`, `Component`, and `GetTypeRegistration`. This
shouldn't affect most existing code as `CameraProjectionPlugin<T>` never
implemented `Plugin` unless those bounds were met.
# Objective
Split up from #12017, add an aligned version of `Direction3d` for SIMD,
and move direction types out of `primitives`.
## Solution
Add `Direction3dA` and move direction types into a new `direction`
module.
---
## Migration Guide
The `Direction2d`, `Direction3d`, and `InvalidDirectionError` types have
been moved out of `bevy::math::primitives`.
Before:
```rust
use bevy::math::primitives::Direction3d;
```
After:
```rust
use bevy::math::Direction3d;
```

# Objective
- Improve compatibility with CSS Module 4
- Simplify `Hsla` conversion functions
## Solution
- Added `Hsva` which implements the HSV color model.
- Added `Hwba` which implements the HWB color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Hsva` / `Hwba` to either `Hsla` or `Srgba` using the provided
`From` implementations and then handle accordingly.
## Notes
While the HSL color space is older than HWB, the formulation for HWB is
more directly related to RGB. Likewise, HSV is more closely related to
HWB than HSL. This makes the conversion of HSL to/from RGB more
naturally represented as the compound operation HSL <-> HSV <-> HWB <->
RGB. All `From` implementations for HSL, HSV, and HWB have been designed
to take the shortest path between itself and the target space.

# Objective
- We should move towards a consistent use of the new `bevy_color` crate.
- As discussed in #12089, splitting this work up into small pieces makes
it easier to review.
## Solution
- Port all uses of `LegacyColor` in the `bevy_core_pipeline` to
`LinearRgba`
- `LinearRgba` is the correct type to use for internal rendering types
- Added `LinearRgba::BLACK` and `WHITE` (used during migration)
- Add `LinearRgba::grey` to more easily construct balanced grey colors
(used during migration)
- Add a conversion from `LinearRgba` to `wgpu::Color`. The converse was
not done at this time, as this is typically a user error.
I did not change the field type of the clear color on the cameras: as
this is user-facing, this should be done in concert with the other
configurable fields.
## Migration Guide
`ColorAttachment` now stores a `LinearRgba` color, rather than a Bevy
0.13 `Color`.
`set_blend_constant` now takes a `LinearRgba` argument, rather than a
Bevy 0.13 `Color`.

# Objective
The physical width and height (pixels) of an image is always integers,
but for `GpuImage` bevy currently stores them as `Vec2` (`f32`).
Switching to `UVec2` makes this more consistent with the [underlying
texture data](https://docs.rs/wgpu/latest/wgpu/struct.Extent3d.html).
I'm not sure if this is worth the change in the surface level API. If
not, feel free to close this PR.
## Solution
- Replace uses of `Vec2` with `UVec2` when referring to texture
dimensions.
- Use integer types for the texture atlas dimensions and sections.
[`Sprite::rect`](a81a2d1da3/crates/bevy_sprite/src/sprite.rs (L29))
remains unchanged, so manually specifying a sub-pixel region of an image
is still possible.
---
## Changelog
- `GpuImage` now stores its size as `UVec2` instead of `Vec2`.
- Texture atlases store their size and sections as `UVec2` and `URect`
respectively.
- `UiImageSize` stores its size as `UVec2`.
## Migration Guide
- Change floating point types (`Vec2`, `Rect`) to their respective
unsigned integer versions (`UVec2`, `URect`) when using `GpuImage`,
`TextureAtlasLayout`, `TextureAtlasBuilder`,
`DynamicAtlasTextureBuilder` or `FontAtlas`.

# Objective
The migration process for `bevy_color` (#12013) will be fairly involved:
there will be hundreds of affected files, and a large number of APIs.
## Solution
To allow us to proceed granularly, we're going to keep both
`bevy_color::Color` (new) and `bevy_render::Color` (old) around until
the migration is complete.
However, simply doing this directly is confusing! They're both called
`Color`, making it very hard to tell when a portion of the code has been
ported.
As discussed in #12056, by renaming the old `Color` type, we can make it
easier to gradually migrate over, one API at a time.
## Migration Guide
THIS MIGRATION GUIDE INTENTIONALLY LEFT BLANK.
This change should not be shipped to end users: delete this section in
the final migration guide!

- Set the pipeline state to queued when it errs waiting for the shader
so that it's retried
This PR closes#11978
# Objective
Fix rendering on iOS Simulators.
iOS Simulator doesn't support the capability CUBE_ARRAY_TEXTURES, since
0.13 this started to make iOS Simulator not render anything with the
following message being outputted:

## Solution
- Split up NO_ARRAY_TEXTURES_SUPPORT into both NO_ARRAY_TEXTURES_SUPPORT
and NO_CUBE_ARRAY_TEXTURES_SUPPORT and correctly apply
NO_ARRAY_TEXTURES_SUPPORT for iOS Simulator using the cfg flag
introduced in #10178.

# Objective
This PR adds some missing mime types to the
`ImageFormat::from_mime_type` method. As discussed [in this comment on
the Discord Bevy
community](https://discord.com/channels/691052431525675048/691052431974465548/1209904290227949729):
> It's strange that Bevy supports parsing `ImageFormat::WebP` from a
.webp str extension in the method below, but not from the mime type.
>
> In comparison, the image crate does parse it:
https://github.com/image-rs/image/blob/master/src/image.rs#L170
# Solution
For each of the missing mime types, I added them based on the
`ImageFormat::from_mime_type` of the image crate:
https://github.com/image-rs/image/blob/master/src/image.rs#L209, except
for `ImageFormat::Basis` and `ImageFormat::Ktx2` which are not present
in the image crate, and I ignore if they have a mime type or not*
\* apparently nowadays there is an official mime type: `image/ktx2`
https://www.iana.org/assignments/media-types/image/ktx2
Any feedback is welcome! I thought of refactoring a bit more and
delegating the mime type parsing to the image crate (and possibly the
same for extensions), let me know if that's desired 🙂

# Objective
- Closes#11985
## Solution
- alpha.rs has been moved from bevy_pbr into bevy_render; bevy_pbr and
bevy_gltf now access `AlphaMode` through bevy_render.
---
## Migration Guide
In the present implementation, external consumers of `AlphaMode` will
have to access it through bevy_render rather than through bevy_pbr,
changing their import from `bevy_pbr::AlphaMode` to
`bevy_render::alpha::AlphaMode` (or the corresponding glob import from
`bevy_pbr::prelude::*` to `bevy_render::prelude::*`).
## Uncertainties
Some remaining things from this that I am uncertain about:
- Here, the `app.register_type<AlphaMode>()` call has been moved from
`PbrPlugin` to `RenderPlugin`; I'm not sure if this is quite right, and
I was unable to find any direct relationship between `PbrPlugin` and
`RenderPlugin`.
- `AlphaMode` was placed in the prelude of bevy_render. I'm not certain
that this is actually appropriate.
- bevy_pbr does not re-export `AlphaMode`, which makes this a breaking
change for external consumers.
Any of these things could be easily changed; I'm just not confident that
I necessarily adopted the right approach in these (known) ways since
this codebase and ecosystem is quite new to me.
Adopted #8266, so copy-pasting the description from there:
# Objective
Support the KHR_texture_transform extension for the glTF loader.
- Fixes#6335
- Fixes#11869
- Implements part of #11350
- Implements the GLTF part of #399
## Solution
As is, this only supports a single transform. Looking at Godot's source,
they support one transform with an optional second one for detail, AO,
and emission. glTF specifies one per texture. The public domain
materials I looked at seem to share the same transform. So maybe having
just one is acceptable for now. I tried to include a warning if multiple
different transforms exist for the same material.
Note the gltf crate doesn't expose the texture transform for the normal
and occlusion textures, which it should, so I just ignored those for
now. (note by @janhohenheim: this is still the case)
Via `cargo run --release --example scene_viewer
~/src/clone/glTF-Sample-Models/2.0/TextureTransformTest/glTF/TextureTransformTest.gltf`:
## Changelog
Support for the
[KHR_texture_transform](https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_texture_transform)
extension added. Texture UVs that were scaled, rotated, or offset in a
GLTF are now properly handled.

# Objective
If multiple cameras render to the same target with MSAA enabled, only
the first and the last camera output will appear in the final output*.
This is because each camera maintains a separate flag to track the
active main texture. The first camera renders to texture A and all
subsequent cameras first write-back from A and then render into texture
B. Hence, camera 3 onwards will overwrite the work of the previous
camera.
\* This would manifest slightly differently if there were other calls to
post_process_write() in a more complex setup.
The is a functional regression from Bevy 0.12.
## Solution
The flag which tracks the active main texture should be shared between
cameras with the same `NormalizedRenderTarget`. Add the
`Arc<AtomicUsize>` to the existing per-target cache.
# Objective
We deprecated quite a few APIs in 0.13. 0.13 has shipped already. It
should be OK to remove them in 0.14's release. Fixes#4059. Fixes#9011.
## Solution
Remove them.
# Objective
There's a repeating pattern of `ThreadLocal<Cell<Vec<T>>>` which is very
useful for low overhead, low contention multithreaded queues that have
cropped up in a few places in the engine. This pattern is surprisingly
useful when building deferred mutation across multiple threads, as noted
by it's use in `ParallelCommands`.
However, `ThreadLocal<Cell<Vec<T>>>` is not only a mouthful, it's also
hard to ensure the thread-local queue is replaced after it's been
temporarily removed from the `Cell`.
## Solution
Wrap the pattern into `bevy_utils::Parallel<T>` which codifies the
entire pattern and ensures the user follows the contract. Instead of
fetching indivdual cells, removing the value, mutating it, and replacing
it, `Parallel::get` returns a `ParRef<'a, T>` which contains the
temporarily removed value and a reference back to the cell, and will
write the mutated value back to the cell upon being dropped.
I would like to use this to simplify the remaining part of #4899 that
has not been adopted/merged.

# Objective
Fixes#11964.
## Solution
Adds the `serde` feature to `bitflags` for `bevy_render`. This makes
`bevy_render` compile correctly when used alone.
---
## Changelog
- Fixed an issue where depending on `bevy_render` alone would fail to
compile.
# Objective
- I hated having to do `Cuboid::new(1.0, 1.0, 1.0)` or
`Cuboid::from_size(Vec3::splat(1.0))` when there should be a much easier
way to do this.
## Solution
- Implemented a `from_length()` method that only takes in a single
float, and constructs a primitive of equal size in all directions.
- Ex:
```rs
// These:
Cuboid::new(1.0, 1.0, 1.0);
Cuboid::from_size(Vec3::splat(1.0));
// Are equivalent to this:
Cuboid::from_length(1.0);
```
- For the rest of the changed primitives:
```rs
Rectangle::from_length(1.0);
Plane3d::default().mesh().from_length(1.0);
```
# Objective
Fixes#11908
## Solution
- Remove the `naga_oil` dependency from `bevy_pbr`.
- We were doing a little dance to disable `glsl` support on not-wasm, so
incorporate that dance into `bevy_render`'s `Cargo.toml`.

This represents when the user has configured `ClearColorConfig::None` in
their application. If the clear color is `None`, we will always `Load`
instead of attempting to clear the attachment on the first call.
Fixes#11883.
# Objective
The new render graph labels do not (and cannot) implement normal
Reflect, which breaks spawning scenes with cameras (including GLTF
scenes). Likewise, the new `CameraMainTextureUsages` also does not (and
cannot) implement normal Reflect because it uses `wgpu::TextureUsages`
under the hood.
Fixes#11852
## Solution
This implements minimal "reflect value" for `CameraRenderGraph` and
`CameraMainTextureUsages` and registers the types, which satisfies our
spawn logic.
Note that this _does not_ fix scene serialization for these types, which
will require more significant changes. We will especially need to think
about how (and if) "interned labels" will fit into the scene system. For
the purposes of 0.13, I think this is the best we can do. Given that
this serialization issue is prevalent throughout Bevy atm, I'm ok with
adding a couple more to the pile. When we roll out the new scene system,
we will be forced to solve these on a case-by-case basis.
---
## Changelog
- Implement Reflect (value) for `CameraMainTextureUsages` and
`CameraRenderGraph`, and register those types.
# Objective
#10644 introduced nice "statically typed" labels that replace the old
strings. I would like to propose some changes to the names introduced:
* `SubGraph2d` -> `Core2d` and `SubGraph3d` -> `Core3d`. The names of
these graphs have been / should continue to be the "core 2d" graph not
the "sub graph 2d" graph. The crate is called `bevy_core_pipeline`, the
modules are still `core_2d` and `core_3d`, etc.
* `Labels2d` and `Labels3d`, at the very least, should not be plural to
follow naming conventions. A Label enum is not a "collection of labels",
it is a _specific_ Label. However I think `Label2d` and `Label3d` is
significantly less clear than `Node2d` and `Node3d`, so I propose those
changes here. I've done the same for `LabelsPbr` -> `NodePbr` and
`LabelsUi` -> `NodeUi`
Additionally, #10644 accidentally made one of the Camera2dBundle
constructors use the 3D graph instead of the 2D graph. I've fixed that
here.
---
## Changelog
* Renamed `SubGraph2d` -> `Core2d`, `SubGraph3d` -> `Core3d`, `Labels2d`
-> `Node2d`, `Labels3d` -> `Node3d`, `LabelsUi` -> `NodeUi`, `LabelsPbr`
-> `NodePbr`
# Objective
After adding configurable exposure, we set the default ev100 value to
`7` (indoor). This brought us out of sync with Blender's configuration
and defaults. This PR changes the default to `9.7` (bright indoor or
very overcast outdoors), as I calibrated in #11577. This feels like a
very reasonable default.
The other changes generally center around tweaking Bevy's lighting
defaults and examples to play nicely with this number, alongside a few
other tweaks and improvements.
Note that for artistic reasons I have reverted some examples, which
changed to directional lights in #11581, back to point lights.
Fixes#11577
---
## Changelog
- Changed `Exposure::ev100` from `7` to `9.7` to better match Blender
- Renamed `ExposureSettings` to `Exposure`
- `Camera3dBundle` now includes `Exposure` for discoverability
- Bumped `FULL_DAYLIGHT ` and `DIRECT_SUNLIGHT` to represent the
middle-to-top of those ranges instead of near the bottom
- Added new `AMBIENT_DAYLIGHT` constant and set that as the new
`DirectionalLight` default illuminance.
- `PointLight` and `SpotLight` now have a default `intensity` of
1,000,000 lumens. This makes them actually useful in the context of the
new "semi-outdoor" exposure and puts them in the "cinema lighting"
category instead of the "common household light" category. They are also
reasonably close to the Blender default.
- `AmbientLight` default has been bumped from `20` to `80`.
## Migration Guide
- The increased `Exposure::ev100` means that all existing 3D lighting
will need to be adjusted to match (DirectionalLights, PointLights,
SpotLights, EnvironmentMapLights, etc). Or alternatively, you can adjust
the `Exposure::ev100` on your cameras to work nicely with your current
lighting values. If you are currently relying on default intensity
values, you might need to change the intensity to achieve the same
effect. Note that in Bevy 0.12, point/spot lights had a different hard
coded ev100 value than directional lights. In Bevy 0.13, they use the
same ev100, so if you have both in your scene, the _scale_ between these
light types has changed and you will likely need to adjust one or both
of them.
# Objective
Fix https://github.com/bevyengine/bevy/issues/11577.
## Solution
Fix the examples, add a few constants to make setting light values
easier, and change the default lighting settings to be more realistic.
(Now designed for an overcast day instead of an indoor environment)
---
I did not include any example-related changes in here.
## Changelogs (not including breaking changes)
### bevy_pbr
- Added `light_consts` module (included in prelude), which contains
common lux and lumen values for lights.
- Added `AmbientLight::NONE` constant, which is an ambient light with a
brightness of 0.
- Added non-EV100 variants for `ExposureSettings`'s EV100 constants,
which allow easier construction of an `ExposureSettings` from a EV100
constant.
## Breaking changes
### bevy_pbr
The several default lighting values were changed:
- `PointLight`'s default `intensity` is now `2000.0`
- `SpotLight`'s default `intensity` is now `2000.0`
- `DirectionalLight`'s default `illuminance` is now
`light_consts::lux::OVERCAST_DAY` (`1000.`)
- `AmbientLight`'s default `brightness` is now `20.0`
# Objective
- The current implementations for `&Visibility == Visibility` and
`Visibility == &Visibility` are ambiguous, so they raise a warning for
being unconditionally recursive.
- `TaskPool`'s `LOCAL_EXECUTOR` thread local calls a `const` constructor
in a non-`const` context.
## Solution
- Make `&Visibility == Visibility` and `Visibility == &Visibility`
implementations use `Visibility == Visibility`.
- Wrap `LocalExecutor::new` in a special `const` block supported by
[`thread_local`](https://doc.rust-lang.org/stable/std/macro.thread_local.html).

# Objective
It can sometimes be useful to combine several meshes into one. This
allows constructing more complex meshes out of simple primitives without
needing to use a 3D modeling program or entity hierarchies.
This could also be used internally to increase code reuse by using
existing mesh generation logic for e.g. circles and using that in
cylinder mesh generation logic to add the top and bottom of the
cylinder.
**Note**: This is *not* implementing CSGs (Constructive Solid Geometry)
or any boolean operations, as that is much more complex. This is simply
adding the mesh data of another mesh to a mesh.
## Solution
Add a `merge` method to `Mesh`. It appends the vertex attributes and
indices of `other` to `self`, resulting in a `Mesh` that is the
combination of the two.
For example, you could do this:
```rust
let mut cuboid = Mesh::from(shape::Box::default());
let mut cylinder = Mesh::from(shape::Cylinder::default());
let mut torus = Mesh::from(shape::Torus::default());
cuboid.merge(cylinder);
cuboid.merge(torus);
```
This would result in `cuboid` being a `Mesh` that also has the cylinder
mesh and torus mesh. In this case, they would just be placed on top of
each other, but by utilizing #11454 we can transform the cylinder and
torus to get a result like this:
https://github.com/bevyengine/bevy/assets/57632562/557402c6-b896-4aba-bd95-312e7d1b5238
This is just a single entity and a single mesh.
# Objective
Reduce the size of `bevy_utils`
(https://github.com/bevyengine/bevy/issues/11478)
## Solution
Move `EntityHash` related types into `bevy_ecs`. This also allows us
access to `Entity`, which means we no longer need `EntityHashMap`'s
first generic argument.
---
## Changelog
- Moved `bevy::utils::{EntityHash, EntityHasher, EntityHashMap,
EntityHashSet}` into `bevy::ecs::entity::hash` .
- Removed `EntityHashMap`'s first generic argument. It is now hardcoded
to always be `Entity`.
## Migration Guide
- Uses of `bevy::utils::{EntityHash, EntityHasher, EntityHashMap,
EntityHashSet}` now have to be imported from `bevy::ecs::entity::hash`.
- Uses of `EntityHashMap` no longer have to specify the first generic
parameter. It is now hardcoded to always be `Entity`.
# Objective
Loading some textures from the days of yonder give me errors cause the
mipmap level is 0
## Solution
Set a minimum of 1
## Changelog
Make mipmap level at least 1
This fixes a `FIXME` in `extract_meshes` and results in a performance
improvement.
As a result of this change, meshes in the render world might not be
attached to entities anymore. Therefore, the `entity` parameter to
`RenderCommand::render()` is now wrapped in an `Option`. Most
applications that use the render app's ECS can simply unwrap the
`Option`.
Note that for now sprites, gizmos, and UI elements still use the render
world as usual.
## Migration guide
* For efficiency reasons, some meshes in the render world may not have
corresponding `Entity` IDs anymore. As a result, the `entity` parameter
to `RenderCommand::render()` is now wrapped in an `Option`. Custom
rendering code may need to be updated to handle the case in which no
`Entity` exists for an object that is to be rendered.
# Objective
The deprecation message of `bevy::render::mesh::shape::Quad` says that
you should use `bevy_math`'s `Quad` instead. But it doesn't exist.
## Solution
Mention the correct primitive: `Rectangle`
# Objective
- Encoding many GPU commands (such as in a renderpass with many draws,
such as the main opaque pass) onto a `wgpu::CommandEncoder` is very
expensive, and takes a long time.
- To improve performance, we want to perform the command encoding for
these heavy passes in parallel.
## Solution
- `RenderContext` can now queue up "command buffer generation tasks"
which are closures that will generate a command buffer when called.
- When finalizing the render context to produce the final list of
command buffers, these tasks are run in parallel on the
`ComputeTaskPool` to produce their corresponding command buffers.
- The general idea is that the node graph will run in serial, but in a
node, instead of doing rendering work, you can add tasks to do render
work in parallel with other node's tasks that get ran at the end of the
graph execution.
## Nodes Parallelized
- `MainOpaquePass3dNode`
- `PrepassNode`
- `DeferredGBufferPrepassNode`
- `ShadowPassNode` (One task per view)
## Future Work
- For large number of draws calls, might be worth further subdividing
passes into 2+ tasks.
- Extend this to UI, 2d, transparent, and transmissive nodes?
- Needs testing - small command buffers are inefficient - it may be
worth reverting to the serial command encoder usage for render phases
with few items.
- All "serial" (traditional) rendering work must finish before parallel
rendering tasks (the new stuff) can start to run.
- There is still only one submission to the graphics queue at the end of
the graph execution. There is still no ability to submit work earlier.
## Performance Improvement
Thanks to @Elabajaba for testing on Bistro.
TLDR: Without shadow mapping, this PR has no impact. _With_ shadow
mapping, this PR gives **~40 more fps** than main.
---
## Changelog
- `MainOpaquePass3dNode`, `PrepassNode`, `DeferredGBufferPrepassNode`,
and each shadow map within `ShadowPassNode` are now encoded in parallel,
giving _greatly_ increased CPU performance, mainly when shadow mapping
is enabled.
- Does not work on WASM or AMD+Windows+Vulkan.
- Added `RenderContext::add_command_buffer_generation_task()`.
- `RenderContext::new()` now takes adapter info
- Some render graph and Node related types and methods now have
additional lifetime constraints.

# Objective
While profiling around to validate the results of #9172, I noticed that
`present_frames` can take a significant amount of time. Digging into the
cause, it seems like we're creating a new `QueryState` from scratch
every frame. This involves scanning the entire World's metadata instead
of just updating its view of the world.
## Solution
Use a `SystemState` argument to cache the `QueryState` to avoid this
construction cost.
## Performance
Against `many_foxes`, this seems to cut the time spent in
`present_frames` by nearly almost 2x. Yellow is this PR, red is main.
# Objective
#11431 and #11688 implemented meshing support for Bevy's new geometric
primitives. The next step is to deprecate the shapes in
`bevy_render::mesh::shape` and to later remove them completely for 0.14.
## Solution
Deprecate the shapes and reduce code duplication by utilizing the
primitive meshing API for the old shapes where possible.
Note that some shapes have behavior that can't be exactly reproduced
with the new primitives yet:
- `Box` is more of an AABB with min/max extents
- `Plane` supports a subdivision count
- `Quad` has a `flipped` property
These types have not been changed to utilize the new primitives yet.
---
## Changelog
- Deprecated all shapes in `bevy_render::mesh::shape`
- Changed all examples to use new primitives for meshing
## Migration Guide
Bevy has previously used rendering-specific types like `UVSphere` and
`Quad` for primitive mesh shapes. These have now been deprecated to use
the geometric primitives newly introduced in version 0.13.
Some examples:
```rust
let before = meshes.add(shape::Box::new(5.0, 0.15, 5.0));
let after = meshes.add(Cuboid::new(5.0, 0.15, 5.0));
let before = meshes.add(shape::Quad::default());
let after = meshes.add(Rectangle::default());
let before = meshes.add(shape::Plane::from_size(5.0));
// The surface normal can now also be specified when using `new`
let after = meshes.add(Plane3d::default().mesh().size(5.0, 5.0));
let before = meshes.add(
Mesh::try_from(shape::Icosphere {
radius: 0.5,
subdivisions: 5,
})
.unwrap(),
);
let after = meshes.add(Sphere::new(0.5).mesh().ico(5).unwrap());
```
# Objective
- Try not to drop the render world on the render thread, and drop the
main world after the render world.
- The render world has a drop check that will panic if it is dropped off
the main thread.
## Solution
- Keep track of where the render world is and wait for it to come back
when the channel resource is dropped.
---
## Changelog
- Wait for the render world when the main world is dropped.
## Migration Guide
- If you were using the pipelined rendering channels,
`MainToRenderAppSender` and `RenderToMainAppReceiver`, they have been
combined into the single resource `RenderAppChannels`.

# Objective
Fix https://github.com/bevyengine/bevy/issues/11657
## Solution
Add a `ReflectKind` enum, add `Reflect::reflect_kind` which returns a
`ReflectKind`, and add `kind` method implementions to `ReflectRef`,
`ReflectMut`, and `ReflectOwned`, which returns a `ReflectKind`.
I also changed `AccessError` to use this new struct instead of it's own
`TypeKind` struct.
---
## Changelog
- Added `ReflectKind`, an enumeration over the kinds of a reflected type
without its data.
- Added `Reflect::reflect_kind` (with default implementation)
- Added implementation for the `kind` method on `ReflectRef`,
`ReflectMut`, and `ReflectOwned` which gives their kind without any
information, as a `ReflectKind`
# Objective
- Fixes#11740
## Solution
- Turned `Mesh::set_indices` into `Mesh::insert_indices` and added
related methods for completeness.
---
## Changelog
- Replaced `Mesh::set_indices(indices: Option<Indices>)` with
`Mesh::insert_indices(indices: Indices)`
- Replaced `Mesh::with_indices(indices: Option<Indices>)` with
`Mesh::with_inserted_indices(indices: Indices)` and
`Mesh::with_removed_indices()` mirroring the API for inserting /
removing attributes.
- Updated the examples and internal uses of the APIs described above.
## Migration Guide
- Use `Mesh::insert_indices` or `Mesh::with_inserted_indices` instead of
`Mesh::set_indices` / `Mesh::with_indices`.
- If you have passed `None` to `Mesh::set_indices` or
`Mesh::with_indices` you should use `Mesh::remove_indices` or
`Mesh::with_removed_indices` instead.

Split up from #11007, fixing most of the remaining work for #10569.
Implement `Meshable` for `Cuboid`, `Sphere`, `Cylinder`, `Capsule`,
`Torus`, and `Plane3d`. This covers all shapes that Bevy has mesh
structs for in `bevy_render::mesh::shapes`.
`Cone` and `ConicalFrustum` are new shapes, so I can add them in a
follow-up, or I could just add them here directly if that's preferrable.
## Solution
Implement `Meshable` for `Cuboid`, `Sphere`, `Cylinder`, `Capsule`,
`Torus`, and `Plane3d`.
The logic is mostly just a copy of the the existing `bevy_render`
shapes, but `Plane3d` has a configurable surface normal that affects the
orientation. Some property names have also been changed to be more
consistent.
The default values differ from the old shapes to make them a bit more
logical:
- Spheres now have a radius of 0.5 instead of 1.0. The default capsule
is equivalent to the default cylinder with the sphere's halves glued on.
- The inner and outer radius of the torus are now 0.5 and 1.0 instead of
0.5 and 1.5 (i.e. the new minor and major radii are 0.25 and 0.75). It's
double the width of the default cuboid, half of its height, and the
default sphere matches the size of the hole.
- `Cuboid` is 1x1x1 by default unlike the dreaded `Box` which is 2x1x1.
Before, with "old" shapes:
Now, with primitive meshing:
I only changed the `3d_shapes` example to use primitives for now. I can
change them all in this PR or a follow-up though, whichever way is
preferrable.
### Sphere API
Spheres have had separate `Icosphere` and `UVSphere` structs, but with
primitives we only have one `Sphere`.
We need to handle this with builders:
```rust
// Existing structs
let ico = Mesh::try_from(Icophere::default()).unwrap();
let uv = Mesh::from(UVSphere::default());
// Primitives
let ico = Sphere::default().mesh().ico(5).unwrap();
let uv = Sphere::default().mesh().uv(32, 18);
```
We could add methods on `Sphere` directly to skip calling `.mesh()`.
I also added a `SphereKind` enum that can be used with the `kind`
method:
```rust
let ico = Sphere::default()
.mesh()
.kind(SphereKind::Ico { subdivisions: 8 })
.build();
```
The default mesh for a `Sphere` is an icosphere with 5 subdivisions
(like the default `Icosphere`).

- Use the `warn_once` macro which internally creates an `AtomicBool`.
Downside: in some case the warning state would have been reset after
recreating the struct carrying the warn state, whereas now it will
always warn only once per program run (For example, if all
`MeshPipeline`s are dropped or the `World` is recreated for
`Local<bool>`/ a `bool` resource, which shouldn't happen over the course
of a standard `App` run).

## Changelog
### Removed
- `FontAtlasWarning` has been removed, but the corresponding warning is
still emitted.
# Objective
- Pipeline compilation is slow and blocks the frame
- Closes https://github.com/bevyengine/bevy/issues/8224
## Solution
- Compile pipelines in a Task on the AsyncComputeTaskPool
---
## Changelog
- Render/compute pipeline compilation is now done asynchronously over
multiple frames when the multi-threaded feature is enabled and on
non-wasm and non-macOS platforms
- Added `CachedPipelineState::Creating`
- Added `PipelineCache::block_on_render_pipeline()`
- Added `bevy_utils::futures::check_ready`
- Added `bevy_render/multi-threaded` cargo feature
## Migration Guide
- Match on the new `Creating` variant for exhaustive matches of
`CachedPipelineState`
# Objective
Fixes#11653
## Solution
- Just added the formats to the docstring, I played around with having
the format appear in the type somehow so that it didn't need to be
written manually in the docstring but it ended up being more trouble
than it was worth.

Frustum computation is nontrivial amount of code private in
`update_frusta` system.
Make it public.
This is needed to decide which entities to spawn/despawn in `Update`
based on camera changes. But if `Update` also changed camera, frustum is
not yet recomputed.
Technically it is probably possible to run an iteration of
`update_frusta` system by a user in `Update` schedule after propagating
`GlobalTransform` to the cameras, but it is easier to just compute
frustum manually using API added in this PR.
Also replace two places where this code is used.

Use `TypeIdMap<T>` instead of `HashMap<TypeId, T>`
- ~~`TypeIdMap` was in `bevy_ecs`. I've kept it there because of
#11478~~
- ~~I haven't swapped `bevy_reflect` over because it doesn't depend on
`bevy_ecs`, but I'd also be happy with moving `TypeIdMap` to
`bevy_utils` and then adding a dependency to that~~
- ~~this is a slight change in the public API of
`DrawFunctionsInternal`, does this need to go in the changelog?~~
## Changelog
- moved `TypeIdMap` to `bevy_utils`
- changed `DrawFunctionsInternal::indices` to `TypeIdMap`
## Migration Guide
- `TypeIdMap` now lives in `bevy_utils`
- `DrawFunctionsInternal::indices` now uses a `TypeIdMap`.

# Objective
Currently the `missing_docs` lint is allowed-by-default and enabled at
crate level when their documentations is complete (see #3492).
This PR proposes to inverse this logic by making `missing_docs`
warn-by-default and mark crates with imcomplete docs allowed.
## Solution
Makes `missing_docs` warn at workspace level and allowed at crate level
when the docs is imcomplete.
# Objective
- Allow prepare windows to run off of the main thread on all platforms.
- Fixes https://github.com/bevyengine/bevy/issues/9964 on all platforms.
## Solution
- Running `prepare_windows` on the main thread on apple platforms is
only mandatory to create surface, which is only needed during window
creation. Split that part into its own system that happens before
`prepare_windows`
- Tested on macOS and iOS
---
## Changelog
- Allow prepare windows to run off main thread on all platforms.
# Objective
- In #9822 I forgot to disable auto sync points on the Extract Schedule.
We want to do this because the Commands on the Extract Schedule should
be applied on the render thread.
# Objective
- Allow prepare windows to run off of the main thread on platforms that
allow it.
- Fixes https://github.com/bevyengine/bevy/issues/9964 on most
platforms.
## Solution
- Conditionally compile prepare windows for different OS's
- Seems like it's only the call to `create_surface` that needs to run on
the main thread here.
- I've only tested this on windows, but I do see prepare windows running
on other threads.
---
## Changelog
- Allow prepare windows to run off main thread on platforms that allow
it.
# Objective
The whole `Cow<'static, str>` naming for nodes and subgraphs in
`RenderGraph` is a mess.
## Solution
Replaces hardcoded and potentially overlapping strings for nodes and
subgraphs inside `RenderGraph` with bevy's labelsystem.
---
## Changelog
* Two new labels: `RenderLabel` and `RenderSubGraph`.
* Replaced all uses for hardcoded strings with those labels
* Moved `Taa` label from its own mod to all the other `Labels3d`
* `add_render_graph_edges` now needs a tuple of labels
* Moved `ScreenSpaceAmbientOcclusion` label from its own mod with the
`ShadowPass` label to `LabelsPbr`
* Removed `NodeId`
* Renamed `Edges.id()` to `Edges.label()`
* Removed `NodeLabel`
* Changed examples according to the new label system
* Introduced new `RenderLabel`s: `Labels2d`, `Labels3d`, `LabelsPbr`,
`LabelsUi`
* Introduced new `RenderSubGraph`s: `SubGraph2d`, `SubGraph3d`,
`SubGraphUi`
* Removed `Reflect` and `Default` derive from `CameraRenderGraph`
component struct
* Improved some error messages
## Migration Guide
For Nodes and SubGraphs, instead of using hardcoded strings, you now
pass labels, which can be derived with structs and enums.

## Future work
* Make `NodeSlot`s also use types. Ideally, we have an enum with unit
variants where every variant resembles one slot. Then to make sure you
are using the right slot enum and make rust-analyzer play nicely with
it, we should make an associated type in the `Node` trait. With today's
system, we can introduce 3rd party slots to a node, and i wasnt sure if
this was used, so I didn't do this in this PR.
## Unresolved Questions
When looking at the `post_processing` example, we have a struct for the
label and a struct for the node, this seems like boilerplate and on
discord, @IceSentry (sowy for the ping)
[asked](https://discord.com/channels/691052431525675048/743663924229963868/1175197016947699742)
if a node could automatically introduce a label (or i completely
misunderstood that). The problem with that is, that nodes like
`EmptyNode` exist multiple times *inside the same* (sub)graph, so there
we need extern labels to distinguish between those. Hopefully we can
find a way to reduce boilerplate and still have everything unique. For
EmptyNode, we could maybe make a macro which implements an "empty node"
for a type, but for nodes which contain code and need to be present
multiple times, this could get nasty...
# Objective
Right now, all assets in the main world get extracted and prepared in
the render world (if the asset's using the RenderAssetPlugin). This is
unfortunate for two cases:
1. **TextureAtlas** / **FontAtlas**: This one's huge. The individual
`Image` assets that make up the atlas are cloned and prepared
individually when there's no reason for them to be. The atlas textures
are built on the CPU in the main world. *There can be hundreds of images
that get prepared for rendering only not to be used.*
2. If one loads an Image and needs to transform it in a system before
rendering it, kind of like the [decompression
example](https://github.com/bevyengine/bevy/blob/main/examples/asset/asset_decompression.rs#L120),
there's a price paid for extracting & preparing the asset that's not
intended to be rendered yet.
------
* References #10520
* References #1782
## Solution
This changes the `RenderAssetPersistencePolicy` enum to bitflags. I felt
that the objective with the parameter is so similar in nature to wgpu's
[`TextureUsages`](https://docs.rs/wgpu/latest/wgpu/struct.TextureUsages.html)
and
[`BufferUsages`](https://docs.rs/wgpu/latest/wgpu/struct.BufferUsages.html),
that it may as well be just like that.
```rust
// This asset only needs to be in the main world. Don't extract and prepare it.
RenderAssetUsages::MAIN_WORLD
// Keep this asset in the main world and
RenderAssetUsages::MAIN_WORLD | RenderAssetUsages::RENDER_WORLD
// This asset is only needed in the render world. Remove it from the asset server once extracted.
RenderAssetUsages::RENDER_WORLD
```
### Alternate Solution
I considered introducing a third field to `RenderAssetPersistencePolicy`
enum:
```rust
enum RenderAssetPersistencePolicy {
/// Keep the asset in the main world after extracting to the render world.
Keep,
/// Remove the asset from the main world after extracting to the render world.
Unload,
/// This doesn't need to be in the render world at all.
NoExtract, // <-----
}
```
Functional, but this seemed like shoehorning. Another option is renaming
the enum to something like:
```rust
enum RenderAssetExtractionPolicy {
/// Extract the asset and keep it in the main world.
Extract,
/// Remove the asset from the main world after extracting to the render world.
ExtractAndUnload,
/// This doesn't need to be in the render world at all.
NoExtract,
}
```
I think this last one could be a good option if the bitflags are too
clunky.
## Migration Guide
* `RenderAssetPersistencePolicy::Keep` → `RenderAssetUsage::MAIN_WORLD |
RenderAssetUsage::RENDER_WORLD` (or `RenderAssetUsage::default()`)
* `RenderAssetPersistencePolicy::Unload` →
`RenderAssetUsage::RENDER_WORLD`
* For types implementing the `RenderAsset` trait, change `fn
persistence_policy(&self) -> RenderAssetPersistencePolicy` to `fn
asset_usage(&self) -> RenderAssetUsages`.
* Change any references to `cpu_persistent_access`
(`RenderAssetPersistencePolicy`) to `asset_usage` (`RenderAssetUsage`).
This applies to `Image`, `Mesh`, and a few other types.
# Objective
The first part of #10569, split up from #11007.
The goal is to implement meshing support for Bevy's new geometric
primitives, starting with 2D primitives. 3D meshing will be added in a
follow-up, and we can consider removing the old mesh shapes completely.
## Solution
Add a `Meshable` trait that primitives need to implement to support
meshing, as suggested by the
[RFC](https://github.com/bevyengine/rfcs/blob/main/rfcs/12-primitive-shapes.md#meshing).
```rust
/// A trait for shapes that can be turned into a [`Mesh`].
pub trait Meshable {
/// The output of [`Self::mesh`]. This can either be a [`Mesh`]
/// or a builder used for creating a [`Mesh`].
type Output;
/// Creates a [`Mesh`] for a shape.
fn mesh(&self) -> Self::Output;
}
```
This PR implements it for the following primitives:
- `Circle`
- `Ellipse`
- `Rectangle`
- `RegularPolygon`
- `Triangle2d`
The `mesh` method typically returns a builder-like struct such as
`CircleMeshBuilder`. This is needed to support shape-specific
configuration for things like mesh resolution or UV configuration:
```rust
meshes.add(Circle { radius: 0.5 }.mesh().resolution(64));
```
Note that if no configuration is needed, you can even skip calling
`mesh` because `From<MyPrimitive>` is implemented for `Mesh`:
```rust
meshes.add(Circle { radius: 0.5 });
```
I also updated the `2d_shapes` example to use primitives, and tweaked
the colors to have better contrast against the dark background.
Before:
After:
Here you can see the UVs and different facing directions: (taken from
#11007, so excuse the 3D primitives at the bottom left)
---
## Changelog
- Added `bevy_render::mesh::primitives` module
- Added `Meshable` trait and implemented it for:
- `Circle`
- `Ellipse`
- `Rectangle`
- `RegularPolygon`
- `Triangle2d`
- Implemented `Default` and `Copy` for several 2D primitives
- Updated `2d_shapes` example to use primitives
- Tweaked colors in `2d_shapes` example to have better contrast against
the (new-ish) dark background

# Objective
It can sometimes be useful to transform actual `Mesh` data without
needing to change the `Transform` of an entity. For example, one might
want to spawn a circle mesh facing up instead of facing Z, or to spawn a
mesh slightly offset without needing child entities.
## Solution
Add `transform_by` and `transformed_by` methods to `Mesh`. They take a
`Transform` and apply the translation, rotation, and scale to vertex
positions, and the rotation to normals and tangents.
In the `load_gltf` example, with this system:
```rust
fn transform(time: Res<Time>, mut q: Query<&mut Handle<Mesh>>, mut meshes: ResMut<Assets<Mesh>>) {
let sin = 0.0025 * time.elapsed_seconds().sin();
for mesh_handle in &mut q {
if let Some(mesh) = meshes.get_mut(mesh_handle.clone_weak()) {
let transform =
Transform::from_rotation(Quat::from_rotation_y(0.75 * time.delta_seconds()))
.with_scale(Vec3::splat(1.0 + sin));
mesh.transform_by(transform);
}
}
}
```
it looks like this:
https://github.com/bevyengine/bevy/assets/57632562/60432456-6d28-4d06-9c94-2f4148f5acd5
# Objective
My motivation are to resolve some of the issues I describe in this
[PR](https://github.com/bevyengine/bevy/issues/11415):
- not being able to easily mapping entities because the current
EntityMapper requires `&mut World` access
- not being able to create my own `EntityMapper` because some components
(`Parent` or `Children`) do not provide any public way of modifying the
inner entities
This PR makes the `MapEntities` trait accept a generic type that
implements `Mapper` to perform the mapping.
This means we don't need to use `EntityMapper` to perform our mapping,
we can use any type that implements `Mapper`. Basically this change is
very similar to what `serde` does. Instead of specifying directly how to
map entities for a given type, we have 2 distinct steps:
- the user implements `MapEntities` to define how the type will be
traversed and which `Entity`s will be mapped
- the `Mapper` defines how the mapping is actually done
This is similar to the distinction between `Serialize` (`MapEntities`)
and `Serializer` (`Mapper`).
This allows networking library to map entities without having to use the
existing `EntityMapper` (which requires `&mut World` access and the use
of `world_scope()`)
## Migration Guide
- The existing `EntityMapper` (notably used to replicate `Scenes` across
different `World`s) has been renamed to `SceneEntityMapper`
- The `MapEntities` trait now works with a generic `EntityMapper`
instead of the specific struct `EntityMapper`.
Calls to `fn map_entities(&mut self, entity_mapper: &mut EntityMapper)`
need to be updated to
`fn map_entities<M: EntityMapper>(&mut self, entity_mapper: &mut M)`
- The new trait `EntityMapper` has been added to the prelude

# Objective
allow automatic fixing of bad joint weights.
fix#10447
## Solution
- remove automatic normalization of vertexes with all zero joint
weights.
- add `Mesh::normalize_joint_weights` which fixes zero joint weights,
and also ensures that all weights sum to 1. this is a manual call as it
may be slow to apply to large skinned meshes, and is unnecessary if you
have control over the source assets.
note: this became a more significant problem with 0.12, as weights that
are close to, but not exactly 1 now seem to use `Vec3::ZERO` for the
unspecified weight, where previously they used the entity translation.
# Objective
After #10520, I was experiencing seriously degraded performance that
ended up being due to never-drained `AssetEvent` events causing havoc
inside `extract_render_asset::<A>`. The same events being read over and
over again meant the same assets were being prepared every frame for
eternity. For what it's worth, I was noticing this on a static scene
about every 3rd or so time running my project.
* References #10520
* Fixes#11240
Why these events aren't sometimes drained between frames is beyond me
and perhaps worthy of another investigation, but the approach in this PR
effectively restores the original cached `EventReader` behavior (which
fixes it).
## Solution
I followed the [`CachedSystemState`
example](3a666cab23/crates/bevy_ecs/src/system/function_system.rs (L155))
to make sure that the `EventReader` state is cached between frames like
it used to be when it was an argument of `extract_render_asset::<A>`.
# Objective
Keep core dependencies up to date.
## Solution
Update the dependencies.
wgpu 0.19 only supports raw-window-handle (rwh) 0.6, so bumping that was
included in this.
The rwh 0.6 version bump is just the simplest way of doing it. There
might be a way we can take advantage of wgpu's new safe surface creation
api, but I'm not familiar enough with bevy's window management to
untangle it and my attempt ended up being a mess of lifetimes and rustc
complaining about missing trait impls (that were implemented). Thanks to
@MiniaczQ for the (much simpler) rwh 0.6 version bump code.
Unblocks https://github.com/bevyengine/bevy/pull/9172 and
https://github.com/bevyengine/bevy/pull/10812
~~This might be blocked on cpal and oboe updating their ndk versions to
0.8, as they both currently target ndk 0.7 which uses rwh 0.5.2~~ Tested
on android, and everything seems to work correctly (audio properly stops
when minimized, and plays when re-focusing the app).
---
## Changelog
- `wgpu` has been updated to 0.19! The long awaited arcanization has
been merged (for more info, see
https://gfx-rs.github.io/2023/11/24/arcanization.html), and Vulkan
should now be working again on Intel GPUs.
- Targeting WebGPU now requires that you add the new `webgpu` feature
(setting the `RUSTFLAGS` environment variable to
`--cfg=web_sys_unstable_apis` is still required). This feature currently
overrides the `webgl2` feature if you have both enabled (the `webgl2`
feature is enabled by default), so it is not recommended to add it as a
default feature to libraries without putting it behind a flag that
allows library users to opt out of it! In the future we plan on
supporting wasm binaries that can target both webgl2 and webgpu now that
wgpu added support for doing so (see
https://github.com/bevyengine/bevy/issues/11505).
- `raw-window-handle` has been updated to version 0.6.
## Migration Guide
- `bevy_render::instance_index::get_instance_index()` has been removed
as the webgl2 workaround is no longer required as it was fixed upstream
in wgpu. The `BASE_INSTANCE_WORKAROUND` shaderdef has also been removed.
- WebGPU now requires the new `webgpu` feature to be enabled. The
`webgpu` feature currently overrides the `webgl2` feature so you no
longer need to disable all default features and re-add them all when
targeting `webgpu`, but binaries built with both the `webgpu` and
`webgl2` features will only target the webgpu backend, and will only
work on browsers that support WebGPU.
- Places where you conditionally compiled things for webgl2 need to be
updated because of this change, eg:
- `#[cfg(any(not(feature = "webgl"), not(target_arch = "wasm32")))]`
becomes `#[cfg(any(not(feature = "webgl") ,not(target_arch = "wasm32"),
feature = "webgpu"))]`
- `#[cfg(all(feature = "webgl", target_arch = "wasm32"))]` becomes
`#[cfg(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))]`
- `if cfg!(all(feature = "webgl", target_arch = "wasm32"))` becomes `if
cfg!(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))`
- `create_texture_with_data` now also takes a `TextureDataOrder`. You
can probably just set this to `TextureDataOrder::default()`
- `TextureFormat`'s `block_size` has been renamed to `block_copy_size`
- See the `wgpu` changelog for anything I might've missed:

# Objective
> Can anyone explain to me the reasoning of renaming all the types named
Query to Data. I'm talking about this PR
https://github.com/bevyengine/bevy/pull/10779 It doesn't make sense to
me that a bunch of types that are used to run queries aren't named Query
anymore. Like ViewQuery on the ViewNode is the type of the Query. I
don't really understand the point of the rename, it just seems like it
hides the fact that a query will run based on those types.

## Solution
Revert several renames in #10779.

# Objective
- Add the ability to describe storage texture bindings when deriving
`AsBindGroup`.
- This is especially valuable for the compute story of bevy which
deserves some extra love imo.
## Solution
- This add the ability to annotate struct fields with a
`#[storage_texture(0)]` annotation.
- Instead of adding specific option parsing for all the image formats
and access modes, I simply accept a token stream and defer checking to
see if the option is valid to the compiler. This still results in useful
and friendly errors and is free to maintain and always compatible with
wgpu changes.
---
## Changelog
- The `#[storage_texture(..)]` annotation is now accepted for fields of
`Handle<Image>` in structs that derive `AsBindGroup`.
- The game_of_life compute shader example has been updated to use
`AsBindGroup` together with `[storage_texture(..)]` to obtain the
`BindGroupLayout`.
## Migration Guide
# Objective
- since #9685 ,bevy introduce automatic batching of draw commands,
- `batch_and_prepare_render_phase` take the responsibility for batching
`phaseItem`,
- `GetBatchData` trait is used for indentify each phaseitem how to
batch. it defines a associated type `Data `used for Query to fetch data
from world.
- however,the impl of `GetBatchData ` in bevy always set ` type
Data=Entity` then we acually get following code
`let entity:Entity =query.get(item.entity())` that cause unnecessary
overhead .
## Solution
- remove associated type `Data ` and `Filter` from `GetBatchData `,
- change the type of the `query_item ` parameter in get_batch_data from`
Self::Data` to `Entity`.
- `batch_and_prepare_render_phase ` no longer takes a query using
`F::Data, F::Filter`
- `get_batch_data `now returns `Option<(Self::BufferData,
Option<Self::CompareData>)>`

This pull request re-submits #10057, which was backed out for breaking
macOS, iOS, and Android. I've tested this version on macOS and Android
and on the iOS simulator.
# Objective
This pull request implements *reflection probes*, which generalize
environment maps to allow for multiple environment maps in the same
scene, each of which has an axis-aligned bounding box. This is a
standard feature of physically-based renderers and was inspired by [the
corresponding feature in Blender's Eevee renderer].
## Solution
This is a minimal implementation of reflection probes that allows
artists to define cuboid bounding regions associated with environment
maps. For every view, on every frame, a system builds up a list of the
nearest 4 reflection probes that are within the view's frustum and
supplies that list to the shader. The PBR fragment shader searches
through the list, finds the first containing reflection probe, and uses
it for indirect lighting, falling back to the view's environment map if
none is found. Both forward and deferred renderers are fully supported.
A reflection probe is an entity with a pair of components, *LightProbe*
and *EnvironmentMapLight* (as well as the standard *SpatialBundle*, to
position it in the world). The *LightProbe* component (along with the
*Transform*) defines the bounding region, while the
*EnvironmentMapLight* component specifies the associated diffuse and
specular cubemaps.
A frequent question is "why two components instead of just one?" The
advantages of this setup are:
1. It's readily extensible to other types of light probes, in particular
*irradiance volumes* (also known as ambient cubes or voxel global
illumination), which use the same approach of bounding cuboids. With a
single component that applies to both reflection probes and irradiance
volumes, we can share the logic that implements falloff and blending
between multiple light probes between both of those features.
2. It reduces duplication between the existing *EnvironmentMapLight* and
these new reflection probes. Systems can treat environment maps attached
to cameras the same way they treat environment maps applied to
reflection probes if they wish.
Internally, we gather up all environment maps in the scene and place
them in a cubemap array. At present, this means that all environment
maps must have the same size, mipmap count, and texture format. A
warning is emitted if this restriction is violated. We could potentially
relax this in the future as part of the automatic mipmap generation
work, which could easily do texture format conversion as part of its
preprocessing.
An easy way to generate reflection probe cubemaps is to bake them in
Blender and use the `export-blender-gi` tool that's part of the
[`bevy-baked-gi`] project. This tool takes a `.blend` file containing
baked cubemaps as input and exports cubemap images, pre-filtered with an
embedded fork of the [glTF IBL Sampler], alongside a corresponding
`.scn.ron` file that the scene spawner can use to recreate the
reflection probes.
Note that this is intentionally a minimal implementation, to aid
reviewability. Known issues are:
* Reflection probes are basically unsupported on WebGL 2, because WebGL
2 has no cubemap arrays. (Strictly speaking, you can have precisely one
reflection probe in the scene if you have no other cubemaps anywhere,
but this isn't very useful.)
* Reflection probes have no falloff, so reflections will abruptly change
when objects move from one bounding region to another.
* As mentioned before, all cubemaps in the world of a given type
(diffuse or specular) must have the same size, format, and mipmap count.
Future work includes:
* Blending between multiple reflection probes.
* A falloff/fade-out region so that reflected objects disappear
gradually instead of vanishing all at once.
* Irradiance volumes for voxel-based global illumination. This should
reuse much of the reflection probe logic, as they're both GI techniques
based on cuboid bounding regions.
* Support for WebGL 2, by breaking batches when reflection probes are
used.
These issues notwithstanding, I think it's best to land this with
roughly the current set of functionality, because this patch is useful
as is and adding everything above would make the pull request
significantly larger and harder to review.
---
## Changelog
### Added
* A new *LightProbe* component is available that specifies a bounding
region that an *EnvironmentMapLight* applies to. The combination of a
*LightProbe* and an *EnvironmentMapLight* offers *reflection probe*
functionality similar to that available in other engines.

# Objective
- Some users want to change the default texture usage of the main camera
but they are currently hardcoded
## Solution
- Add a component that is used to configure the main texture usage field
---
## Changelog
Added `CameraMainTextureUsage`
Added `CameraMainTextureUsage` to `Camera3dBundle` and `Camera2dBundle`
## Migration Guide
Add `main_texture_usages: Default::default()` to your camera bundle.
# Notes
Inspired by: #6815
# Objective
- `DynamicUniformBuffer::push` takes an owned `T` but only uses a shared
reference to it
- This in turn requires users of `DynamicUniformBuffer::push` to
potentially unecessarily clone data
## Solution
- Have `DynamicUniformBuffer::push` take a shared reference to `T`
---
## Changelog
- `DynamicUniformBuffer::push` now takes a `&T` instead of `T`
## Migration Guide
- Users of `DynamicUniformBuffer::push` now need to pass references to
`DynamicUniformBuffer::push` (e.g. existing `uniforms.push(value)` will
now become `uniforms.push(&value)`)
Rebased and finished version of
https://github.com/bevyengine/bevy/pull/8407. Huge thanks to @GitGhillie
for adjusting all the examples, and the many other people who helped
write this PR (@superdump , @coreh , among others) :)
Fixes https://github.com/bevyengine/bevy/issues/8369
---
## Changelog
- Added a `brightness` control to `Skybox`.
- Added an `intensity` control to `EnvironmentMapLight`.
- Added `ExposureSettings` and `PhysicalCameraParameters` for
controlling exposure of 3D cameras.
- Removed the baked-in `DirectionalLight` exposure Bevy previously
hardcoded internally.
## Migration Guide
- If using a `Skybox` or `EnvironmentMapLight`, use the new `brightness`
and `intensity` controls to adjust their strength.
- All 3D scene will now have different apparent brightnesses due to Bevy
implementing proper exposure controls. You will have to adjust the
intensity of your lights and/or your camera exposure via the new
`ExposureSettings` component to compensate.

# Objective
Add support for presenting each UI tree on a specific window and
viewport, while making as few breaking changes as possible.
This PR is meant to resolve the following issues at once, since they're
all related.
- Fixes#5622
- Fixes#5570
- Fixes#5621
Adopted #5892 , but started over since the current codebase diverged
significantly from the original PR branch. Also, I made a decision to
propagate component to children instead of recursively iterating over
nodes in search for the root.
## Solution
Add a new optional component that can be inserted to UI root nodes and
propagate to children to specify which camera it should render onto.
This is then used to get the render target and the viewport for that UI
tree. Since this component is optional, the default behavior should be
to render onto the single camera (if only one exist) and warn of
ambiguity if multiple cameras exist. This reduces the complexity for
users with just one camera, while giving control in contexts where it
matters.
## Changelog
- Adds `TargetCamera(Entity)` component to specify which camera should a
node tree be rendered into. If only one camera exists, this component is
optional.
- Adds an example of rendering UI to a texture and using it as a
material in a 3D world.
- Fixes recalculation of physical viewport size when target scale factor
changes. This can happen when the window is moved between displays with
different DPI.
- Changes examples to demonstrate assigning UI to different viewports
and windows and make interactions in an offset viewport testable.
- Removes `UiCameraConfig`. UI visibility now can be controlled via
combination of explicit `TargetCamera` and `Visibility` on the root
nodes.

# Objective
- Update async channel to v2.
## Solution
- async channel doesn't support `send_blocking` on wasm anymore. So
don't compile the pipelined rendering plugin on wasm anymore.
- Replaces https://github.com/bevyengine/bevy/pull/10405
## Migration Guide
- The `PipelinedRendering` plugin is no longer exported on wasm. If you
are including it in your wasm builds you should remove it.
```rust
#[cfg(all(not(target_arch = "wasm32"))]
app.add_plugins(bevy_render::pipelined_rendering::PipelinedRenderingPlugin);

# Objective
Issue #10243: rendering multiple triangles in the same place results in
flickering.
## Solution
Considered these alternatives:
- `depth_bias` may not work, because of high number of entities, so
creating a material per entity is practically not possible
- rendering at slightly different positions does not work, because when
camera is far, float rounding causes the same issues (edit: assuming we
have to use the same `depth_bias`)
- considered implementing deterministic operation like
`query.par_iter().flat_map(...).collect()` to be used in
`check_visibility` system (which would solve the issue since query is
deterministic), and could not figure out how to make it as cheap as
current approach with thread-local collectors (#11249)
So adding an option to sort entities after `check_visibility` system
run.
Should not be too bad, because after visibility check, only a handful
entities remain.
This is probably not the only source of non-determinism in Bevy, but
this is one I could find so far. At least it fixes the repro example.
## Changelog
- `DeterministicRenderingConfig` option to enable deterministic
rendering

# Objective
- Since #10702, the way bevy updates the window leads to major slowdowns
as seen in
- #11122
- #11220
- Slow is bad, furthermore, _very_ slow is _very_ bad. We should fix
this issue.
## Solution
- Move the app update code into the `Event::WindowEvent { event:
WindowEvent::RedrawRequested }` branch of the event loop.
- Run `window.request_redraw()` When `runner_state.redraw_requested`
- Instead of swapping `ControlFlow` between `Poll` and `Wait`, we always
keep it at `Wait`, and use `window.request_redraw()` to schedule an
immediate call to the event loop.
- `runner_state.redraw_requested` is set to `true` when
`UpdateMode::Continuous` and when a `RequestRedraw` event is received.
- Extract the redraw code into a separate function, because otherwise
I'd go crazy with the indentation level.
- Fix#11122.
## Testing
I tested the WASM builds as follow:
```sh
cargo run -p build-wasm-example -- --api webgl2 bevymark
python -m http.server --directory examples/wasm/ 8080
# Open browser at http://localhost:8080
```
On main, even spawning a couple sprites is super choppy. Even if it says
"300 FPS". While on this branch, it is smooth as butter.
I also found that it fixes all choppiness on window resize (tested on
Linux/X11). This was another issue from #10702 IIRC.
So here is what I tested:
- On `wasm`: `many_foxes` and `bevymark`, with `argh::from_env()`
commented out, otherwise we get a cryptic error.
- Both with `PresentMode::AutoVsync` and `PresentMode::AutoNoVsync`
- On main, it is consistently choppy.
- With this PR, the visible frame rate is consistent with the diagnostic
numbers
- On native (linux/x11) I ran similar tests, making sure that
`AutoVsync` limits to monitor framerate, and `AutoNoVsync` doesn't.
## Future work
Code could be improved, I wanted a quick solution easy to review, but we
really need to make the code more accessible.
- #9768
- ~~**`WinitSettings::desktop_app()` is completely borked.**~~ actually
broken on main as well
### Review guide
Consider enable the non-whitespace diff to see the _real_ change set.
# Objective
- Since #10520, assets are unloaded from RAM by default. This breaks a
number of scenario:
- using `load_folder`
- loading a gltf, then going through its mesh to transform them /
compute a collider / ...
- any assets/subassets scenario should be `Keep` as you can't know what
the user will do with the assets
- android suspension, where GPU memory is unloaded
- Alternative to #11202
## Solution
- Keep assets on CPU memory by default
