# Objective
Add XYZ colour space. This will be most useful as a conversion step when
working with other (more common) colour spaces. See
[Wikipedia](https://en.wikipedia.org/wiki/CIE_1931_color_space) for
details on this space.
## Solution
- Added `Xyza` to `Color` and as its own type.
---
## Changelog
- Added `Xyza` type.
- Added `Color::Xyza` variant.
## Migration Guide
- `Color` enum now has an additional member, `Xyza`. Convert it to any
other type to handle this case in match statements.
# Objective
- Fix a wrongly named type
## Solution
- Rename it properly

# Objective
Fixes#11821.
## Solution
* Run `System::apply_deferred` in `System::run` after executing the
system.
* Switch to using `System::run_unsafe` in `SingleThreadedExecutor` to
preserve the current behavior.
* Remove the `System::apply_deferred` in `SimpleExecutor` as it's now
redundant.
* Remove the `System::apply_deferred` when running one-shot systems, as
it's now redundant.
---
## Changelog
Changed: `System::run` will now immediately apply deferred system params
after running the system.
## Migration Guide
`System::run` will now always run `System::apply_deferred` immediately
after running the system now. If you were running systems and then
applying their deferred buffers at a later point in time, you can
eliminate the latter.
```rust
// in 0.13
system.run(world);
// .. sometime later ...
system.apply_deferred(world);
// in 0.14
system.run(world);

# Objective
Since #9822, `SimpleExecutor` panics when an automatic sync point is
inserted:
```rust
let mut sched = Schedule::default();
sched.set_executor_kind(ExecutorKind::Simple);
sched.add_systems((|_: Commands| (), || ()).chain());
sched.run(&mut World::new());
```
```
System's param_state was not found. Did you forget to initialize this system before running it?
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Encountered a panic in system `bevy_ecs::schedule::executor::apply_deferred`!
```
## Solution
Don't try to run the `apply_deferred` system.
# Objective
Fixes Skyboxes on WebGL, which broke in Bevy 0.13 due to the addition of
the `brightness` uniform, when previously the skybox pipeline only had
view and global uniforms.
```ignore
panicked at ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/wgpu-0.19.1/src/backend/wgpu_core.rs:3009:5:
wgpu error: Validation Error
Caused by:
In Device::create_render_pipeline
note: label = `skybox_pipeline`
In the provided shader, the type given for group 0 binding 3 has a size of 4. As the device does not support `DownlevelFlags::BUFFER_BINDINGS_NOT_16_BYTE_ALIGNED`, the type must have a size that is a multiple of 16 bytes.
```
It would be nice if this could be backported to a 0.13.1 patch as well
if possible. I'm needing to rely on my own fork for now.
## Solution
Similar to the Globals uniform solution here:
d31de3f139/crates/bevy_render/src/globals.rs (L59-L60)
I've added 3 conditional fields to `SkyboxUniforms`.
# Objective
`Scope::spawn`, `Scope::spawn_on_external`, and `Scope::spawn_on_scope`
have different signatures depending on whether the `multi-threaded`
feature is enabled. The single-threaded version has a stricter signature
that prevents sending the `Scope` itself to spawned tasks.
## Solution
Changed the lifetime constraints in the single-threaded signatures from
`'env` to `'scope` to match the multi-threaded version.
This was split off from #11906.
# Objective
- Assist Bevy contributors in the creation of `bevy_color` spaces by
ensuring consistent API implementation.
## Solution
Created a `pub(crate)` trait `StandardColor` which has all the
requirements for a typical color space (e.g, `Srgba`, `Color`, etc.).
---
## Changelog
- Implemented traits missing from certain color spaces.
## Migration Guide
_No migration required_
# Objective
Improve code quality and prevent bugs.
## Solution
I removed the unnecessary wildcards from `<LogPlugin as Plugin>::build`.
I also changed the warnings that would occur if the subscriber/logger
was already set into errors.
# Objective
This provides a new set of color types and operations for Bevy.
Fixes: #10986#1402
## Solution
The new crate provides a set of distinct types for various useful color
spaces, along with utilities for manipulating and converting colors.
This is not a breaking change, as no Bevy APIs are modified (yet).

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:

- The `touch_screen_input_system` system runs on every tick.
- It unconditionally calls `update(&mut self)`, on the `Touches`

- Remove `update(&mut self)` as it's only used in this one system, and
in-lining the method implementation removes an indirection to an
ambiguously named method.

## Objective
Always have `some_system.into_system().type_id() ==
some_system.into_system_set().system_type().unwrap()`.
System sets have a `fn system_type() -> Option<TypeId>` that is
implemented by `SystemTypeSet` to returning the TypeId of the system's
function type. This was implemented in
https://github.com/bevyengine/bevy/pull/7715 and is used in
`bevy_mod_debugdump` to handle `.after(function)` constraints.
Back then, `System::type_id` always also returned the type id of the
function item, not of `FunctionSystem<M, F>`.
https://github.com/bevyengine/bevy/pull/11728 changes the behaviour of
`System::type_id` so that it returns the id of the
`FunctionSystem`/`ExclusiveFunctionSystem` wrapper, but it did not
change `SystemTypeSet::system_type`, so doing the lookup breaks in
`bevy_mod_debugdump`.
## Solution
Change `IntoSystemSet` for functions to return a
`SystemTypeSet<FunctionSystem>` /
`SystemTypeSet<ExclusiveFunctionSystem>` instead of `SystemTypeSet<F>`.
# Objective
- Globals are supposed to be available in vertex shader but that was
mistakenly removed in 0.13
## Solution
- Configure the visibility of the globals correctly
Fixes https://github.com/bevyengine/bevy/issues/12015
# Objective
- The file asset source currently creates the `imported_assets/Default`
directory with relative path, which leads to wrongly created directories
when the executable is run with a working directory different from the
project root.
## Solution
- Use the full path instead.

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 🙂
Fixes#12016.

# 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
- Save 16 bytes per MeshUniform in uniform/storage buffers.
## Solution
- Reorder members of MeshUniform to capitalise on alignment and size
rules for tighter data packing. Before the size of a MeshUniform was 160
bytes, and after it is 144 bytes, saving 16 bytes of unused padding for
alignment.
---
## Changelog
- Reduced the size of MeshUniform by 16 bytes.
# Objective

```
Which is very confusing
## Solution
Comment the `derive` attribute as well

# Objective
* Fixes#11932 (performance impact when stepping is disabled)
## Solution
The `Option<FixedBitSet>` argument added to `ScheduleExecutor::run()` in
#8453 caused a measurable performance impact even when stepping is
disabled. This can be seen by the benchmark of running `Schedule:run()`
on an empty schedule in a tight loop
(https://github.com/bevyengine/bevy/issues/11932#issuecomment-1950970236).
I was able to get the same performance results as on 0.12.1 by changing
the argument
`ScheduleExecutor::run()` from `Option<FixedBitSet>` to
`Option<&FixedBitSet>`. The down-side of this change is that
`Schedule::run()` now takes about 6% longer (3.7319 ms vs 3.9855ns) when
stepping is enabled
---
## Changelog
* Change `ScheduleExecutor::run()` `_skipped_systems` from
`Option<FixedBitSet>` to `Option<&FixedBitSet>`
* Added a few benchmarks to measure `Schedule::run()` performance with
various executors
# Objective
- Gltf loader now shows which file is missing pre baked tangents
- Fixes#11831
## Solution
- The file name is shown in the error message
- What changed as a result of this PR?
### Changed:
- Gltf loader now shows which file is missing pre baked tangents
- If this PR is a breaking change (relative to the last release of
Bevy), describe how a user might need to migrate their code to support
these changes
- Simply adding new functionality is not a breaking change.
- Fixing behavior that was definitely a bug, rather than a questionable
design choice is not a breaking change.
# Objective
Currently, the `ambiguous_names` hash set in `TypeRegistry` is used to
keep track of short type names that are ambiguous, and to require the
use of long type names for these types.
However, there's no way for the consumer of `TypeRegistry` to known
whether a given call to `get_with_short_type_path()` or
`get_with_short_type_path_mut()` failed because a type was not
registered at all, or because the short name is ambiguous.
This can be used, for example, for better error reporting to the user by
an editor tool. Here's some code that uses this, from my remote protocol
exploration branch:
```rust
let type_registration = type_registry
.get_with_type_path(component_name)
.or_else(|| registry.get_with_short_type_path(component_name))
.ok_or_else(|| {
if type_registry.is_ambiguous(component_name) {
BrpError::ComponentAmbiguous(component_name.clone())
} else {
BrpError::MissingTypeRegistration(component_name.clone())
}
})?
```
## Solution
- Introduces a `is_ambiguous()` method.
- Also drive-by fixes two documentation comments that had broken links.
---
## Changelog
- Added a `TypeRegistry::is_ambiguous()` method, for checking whether a
given short type path is ambiguous (e.g. `MyType` potentially matching
either `some_crate::MyType` or `another_crate::MyType`)

# Objective
Implement Debug trait for SpriteBundle and SpriteSheetBundle
It's helpful and other basic bundles like TransformBundle and
VisibilityBundle already implement this trait
# 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
Bevy's animation system currently does tree traversals based on `Name`
that aren't necessary. Not only do they require in unsafe code because
tree traversals are awkward with parallelism, but they are also somewhat
slow, brittle, and complex, which manifested itself as way too many
queries in #11670.
# Solution
Divide animation into two phases: animation *advancement* and animation
*evaluation*, which run after one another. *Advancement* operates on the
`AnimationPlayer` and sets the current animation time to match the game
time. *Evaluation* operates on all animation bones in the scene in
parallel and sets the transforms and/or morph weights based on the time
and the clip.
To do this, we introduce a new component, `AnimationTarget`, which the
asset loader places on every bone. It contains the ID of the entity
containing the `AnimationPlayer`, as well as a UUID that identifies
which bone in the animation the target corresponds to. In the case of
glTF, the UUID is derived from the full path name to the bone. The rule
that `AnimationTarget`s are descendants of the entity containing
`AnimationPlayer` is now just a convention, not a requirement; this
allows us to eliminate the unsafe code.
# Migration guide
* `AnimationClip` now uses UUIDs instead of hierarchical paths based on
the `Name` component to refer to bones. This has several consequences:
- A new component, `AnimationTarget`, should be placed on each bone that
you wish to animate, in order to specify its UUID and the associated
`AnimationPlayer`. The glTF loader automatically creates these
components as necessary, so most uses of glTF rigs shouldn't need to
change.
- Moving a bone around the tree, or renaming it, no longer prevents an
`AnimationPlayer` from affecting it.
- Dynamically changing the `AnimationPlayer` component will likely
require manual updating of the `AnimationTarget` components.
* Entities with `AnimationPlayer` components may now possess descendants
that also have `AnimationPlayer` components. They may not, however,
animate the same bones.
* As they aren't specific to `TypeId`s,
`bevy_reflect::utility::NoOpTypeIdHash` and
`bevy_reflect::utility::NoOpTypeIdHasher` have been renamed to
`bevy_reflect::utility::NoOpHash` and
`bevy_reflect::utility::NoOpHasher` respectively.
# Objective
- having different field names for `Camera2dBundle` and `Camera3dBundle`
implies that there is something different between these fields when
there is not
## Solution
- rename the field in `Camera3dBundle` to align with `Camera2dBundle`
## Migration Guide
- use the new `deband_dither` field name with `Camera3dBundle`, rather
than the old field name, `dither`
# Objective

## Changelog
- Fixed an issue where depending on `bevy_render` alone would fail to
compile.
# Objective

`App::is_plugin_added`, use `plugin.is::<T>()`. Which is more performant
and cleaner.
# Objective
- Fixes#11960
- The compilation of `bevy_core_pipeline` failed with the `dds` feature

# Objective
`update_archetype_component_access` was removed from queries in #9774,
but some documentation still refers to it.

Update the documentation. Since a bunch of these were in SAFETY comments
it would be nice if someone who knows the details better could check
that the rest of those comments are still valid.
# Objective
Right now, if you call `embedded_asset` with 2 arguments as a qualified
path it doesn't work (`bevy::asset::embedded_asset!(app, "foo.wgsl")` ->
"cannot find macro `embedded_asset` in this scope")
## Solution
Use `$crate::` in expansion for 2-arg case.
# 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
Another PR failed CI due to duplicate deps, and I noticed this one in
particular while scanning through the error messages.
I think this was missed in #11082.
## Solution
Bump `encase_derive_impl` dep in `bevy_encase_derive` to same version as
`encase` dep for `bevy_render`.
I spot-checked a few examples, and glanced at the
[changelog](<https://github.com/teoxoy/encase/blob/main/CHANGELOG.md#v070-2024-01-02>)
and I don't think there's anything to be concerned about, but I barely
know what this thing does.
# 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`.
They cause the number of texture bindings to overflow on those
platforms. Ultimately, we shouldn't unconditionally disable them, but
this fixes a crash blocking 0.13.
Closes#11885.
I did this during the prepass, but I neglected to do it during the
shadow map pass, causing a panic when directional lights with shadows
were enabled with lightmapped meshes present. This patch fixes the
issue.
Closes#11898.

# Objective
When registering and preregistering asset loaders, there would be a
`warn!` if multiple asset loaders use a given extension, and an `info!`
if multiple asset loaders load the same asset type. Since both of these
situations are individually fine, it was decided that these messages
should be removed.
## Solution
Replace both of these messages with a new `warn!` that notes that if
multiple asset loaders share the same asset type _and_ share extensions,
that the loader must be specified in the `.meta` file for those assets
in order to solve the ambiguity. This is a more useful message, since it
notes when a user must take special action / consideration.
# Objective
Fixes#11846
## Solution
Add a `synchronous_pipeline_compilation ` field to `RenderPlugin`,
defaulting to `false`.
Most of the diff is whitespace.
## Changelog
Added `synchronous_pipeline_compilation ` to `RenderPlugin` for
disabling async pipeline creation.
## Migration Guide
TODO: consider combining this with the guide for #11846
`RenderPlugin` has a new `synchronous_pipeline_compilation ` property.
The default value is `false`. Set this to `true` if you want to retain
the previous synchronous behavior.

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
Provide a public replacement for `Into<MeshUniform>` trait impl which
was removed by #10231.
I made use of this in the `bevy_mod_outline` crate and will have to
duplicate this function if it's not accessible.
## Solution
Change the MeshUniform::new() method to be public.
# 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
- There are multiple instances of `let Some(x) = ... else { None };`
throughout the project.
- Because `Option<T>` implements
[`Try`](https://doc.rust-lang.org/stable/std/ops/trait.Try.html), it can
use the question mark `?` operator.
## Solution
- Use question mark operator instead of `let Some(x) = ... else { None
}`.

There was another PR that did a similar thing a few weeks ago, but I
couldn't find it.
# Objective
I tried using `insert_gizmo_group` to configure my physics gizmos in a
bevy_xpbd example, but was surprised to see that nothing happened. I
found out that the method does *not* overwrite gizmo groups that have
already been initialized (with `init_gizmo_group`). This is unexpected,
since methods like `insert_resource` *do* overwrite.
## Solution
Insert the configuration even if it has already been initialized.
# Objective
`RenderMeshInstance::material_bind_group_id` is only set from
`queue_material_meshes::<M>`. this field is used (only) for determining
batch groups, so some items may be batched incorrectly if they have
never been in the camera's view or if they don't use the Material
abstraction.
in particular, shadow views render more meshes than the main camera, and
currently batch some meshes where the object has never entered the
camera view together. this is quite hard to trigger, but should occur in
a scene with out-of-view alpha-mask materials (so that the material
instance actually affects the shadow) in the path of a light.
this is also a footgun for custom pipelines: failing to set the
material_bind_group_id will result in all meshes being batched together
and all using the closest/furthest material to the camera (depending on
sort order).
## Solution
- queue_shadows now sets the material_bind_group_id correctly
- `MeshPipeline` doesn't attempt to batch meshes if the
material_bind_group_id has not been set. custom pipelines still need to
set this field to take advantage of batching, but will at least render
correctly if it is not set
# Objective
sysinfo was updated to 0.30 in #11071. Ever since then the `cpu` field
of the `SystemInfo` struct that gets printed every time one starts an
bevy app has been empty. This is because the following part of the
sysinfo migration guide was overlooked:
---
### `Cpu` changes
Information like `Cpu::brand`, `Cpu::vendor_id` or `Cpu::frequency` are
not set on the "global" CPU.
---
## Solution
- Get the CPU brand information from a specific CPU instead. In this
case, just choose the first one. It's theoretically possible for
different CPUs to have different names, but in practice this doesn't
really happen I think. Even Intel's newer hybrid processors use a
uniform name for all CPUs in my experience.
- We can use this opportunity to also update our `sysinfo::System`
initialization here to only fetch the information we're interested in.
Make the renamings/changes regarding texture atlases a bit less
confusing by calling `TextureAtlasLayout` a layout, not a texture atlas.

# 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
- Fixes#11782.
## Solution
- Remove the run condition for `apply_global_wireframe_material`, since
it prevent detecting when meshes are added or the `NoWireframe` marker
component is removed from an entity. Alternatively this could be done by
using a run condition like "added `Handle<Mesh>` or removed
`NoWireframe` or `WireframeConfig` changed" but this seems less clear to
me than directly letting the queries on
`apply_global_wireframe_material` do the filtering.
# Objective
-
[`crossbeam::scope`](https://docs.rs/crossbeam/latest/crossbeam/fn.scope.html)
is soft-deprecated in favor of the standard library's implementation.
## Solution
- Replace reference in `TaskPool`'s docs to mention `std:🧵:scope`
instead.
# Objective
- Fixes#11695
## Solution
- Added `delta: Option<Vec2>` to `bevy_window::CursorMoved`. `delta` is
an `Option` because the `CursorMoved` event does get fired when the
cursor was outside the window area in the last frame. In that case there
is no cursor position from the last frame to compare with the current
cursor position.
---
## Changelog
- Added `delta: Option<Vec2>` to `bevy_window::CursorMoved`.
## Migration Guide
- You need to add `delta` to any manually created `CursorMoved` struct.

# Objective
- Fixes#11638
- See
[here](https://github.com/bevyengine/bevy/issues/11638#issuecomment-1920508465)
for details on the cause of this issue.
## Solution
- Modified `AssetLoaders` to capture possibility of multiple
`AssetLoader` registrations operating on the same `Asset` type, but
different extensions.
- Added an algorithm which will attempt to resolve via `AssetLoader`
name, then `Asset` type, then by extension. If at any point multiple
loaders fit a particular criteria, the next criteria is used as a tie
breaker.
# Objective
At the start of every schedule run, there's currently a guaranteed piece
of overhead as the async executor spawns the MultithreadeExecutor task
onto one of the ComputeTaskPool threads.
## Solution
Poll the executor once to immediately schedule systems without waiting
for the async executor, then spawn the task if and only if the executor
does not immediately terminate.
On a similar note, having the executor task immediately start executing
a system in the same async task might yield similar results over a
broader set of cases. However, this might be more involved, and may need
a solution like #8304.
# Objective
When applying a command, we currently use double indirection for the
world reference `&mut Option<&mut World>`. Since this is used across a
`fn` pointer boundary, this can't get optimized away.
## Solution
Reborrow the world reference and pass `Option<&mut World>` instead.
# Objective
Scheduling low cost systems has significant overhead due to task pool
contention and the extra machinery to schedule and run them. Following
the example of #7728, `asset_events` is good example of this kind of
system, where there is no work to be done when there are no queued asset
events.
## Solution
Put a run condition on it that checks if there are any queued events.
## Performance
Tested against `many_foxes`, we can see a slight improvement in the
total time spent in `UpdateAssets`. Also noted much less volatility due
to not being at the whim of the OS thread scheduler.

# Objective
The code in `bevy_reflect_derive` could use some cleanup.
## Solution
Took some of the changes in #11659 to create a dedicated PR for cleaning
up the field and container attribute logic.
#### Updated Naming
I renamed `ReflectTraits` and `ReflectFieldAttr` to
`ContainerAttributes` and `FieldAttributes`, respectively. I think these
are clearer.
#### Updated Parsing
##### Readability
The parsing logic wasn't too bad before, but it was getting difficult to
read. There was some duplicated logic between `Meta::List` and
`Meta::Path` attributes. Additionally, all the logic was kept inside a
large method.
To simply things, I replaced the nested meta parsing with `ParseStream`
parsing. In my opinion, this is easier to follow since it breaks up the
large match statement into a small set of single-line if statements,
where each if-block contains a single call to the appropriate attribute
parsing method.
##### Flexibility
On top of the added simplicity, this also makes our attribute parsing
much more flexible. It allows us to more elegantly handle custom where
clauses (i.e. `#[reflect(where T: Foo)]`) and it opens the door for more
non-standard attribute syntax (e.g. #11659).
##### Errors
This also allows us to automatically provide certain errors when
parsing. For example, since we can use `stream.lookahead1()`, we get
errors like the following for free:
```
error: expected one of: `ignore`, `skip_serializing`, `default`
--> crates/bevy_reflect/src/lib.rs:1988:23

```
---
## Changelog
> [!note]
> All changes are internal to `bevy_reflect_derive` and should not
affect the public API[^1].
- Renamed `ReflectTraits` to `ContainerAttributes`
- Renamed `ReflectMeta::traits` to `ReflectMeta::attrs`
- Renamed `ReflectFieldAttr` to `FieldAttributes`
- Updated parsing logic for field/container attribute parsing
- Now uses a `ParseStream` directly instead of nested meta parsing
- General code cleanup of the field/container attribute modules for
`bevy_reflect_derive`

# Objective
Bevy's change detection functionality is invaluable for writing robust
apps, but it only works in the context of systems and exclusive systems.
Oftentimes it is necessary to detect changes made in earlier code
without having to place the code in separate systems, but it is not
currently possible to do so since there is no way to set the value of
`World::last_change_tick`.
`World::clear_trackers` allows you to update the change tick, but this
has unintended side effects, since it irreversibly affects the behavior
of change and removal detection for the entire app.
## Solution
Add a method `World::last_change_tick_scope`. This allows you to set
`last_change_tick` to a specific value for a region of code. To ensure
that misuse doesn't break unrelated functions, we restore the world's
original change tick at the end of the provided scope.
### Example
A function that uses this to run an update loop repeatedly, allowing
each iteration of the loop to react to changes made in the previous loop
iteration.
```rust
fn update_loop(
world: &mut World,
mut update_fn: impl FnMut(&mut World) -> std::ops::ControlFlow<()>,
) {
let mut last_change_tick = world.last_change_tick();
// Repeatedly run the update function until it requests a break.
loop {
// Update once.
let control_flow = world.last_change_tick_scope(last_change_tick, |world| {
update_fn(world)
});
// End the loop when the closure returns `ControlFlow::Break`.
if control_flow.is_break() {
break;
}
// Increment the change tick so the next update can detect changes from this update.
last_change_tick = world.change_tick();
world.increment_change_tick();
}
}
```
---
## Changelog
+ Added `World::last_change_tick_scope`, which allows you to specify the
reference for change detection within a certain scope.
# Objective
- Part of #11590.
## Solution
- Fix `unsafe_op_in_unsafe_fn` for `bevy_dynamic_plugin`.
---
## Changelog
- Added further restrictions to the safety requirements of
`bevy_dynamic_plugin::dynamically_load_plugin`.
---
I had a few issues, specifically with the safety comment on
`dynamically_load_plugin`. There are three different unsafe functions
called within the function body, and they all need their own
justification / message.
Also, would it be unsound to call `dynamically_load_plugin` multiple
times on the same file? I feel the documentation needs to be more clear.
# 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
# Objective
Use `GamepadButtonType` with library that requires `Ord`.
## Motivation
`KeyCode` derives `Ord` that I'm using with a trie for recognizing
[input
sequences](https://github.com/shanecelis/bevy-input-sequence/tree/trie).
I would like to do the same for `GamepadButtonType` but am stymied by it
not deriving `Ord`.
## Solution
This PR add derivations PartialOrd and Ord for `GamepadButtonType`.
## Workaround
If deriving `Ord` is not possible, I'd be happy to know how I might
coerce `GamepadButtonType` into a `u32` or something else that is `Ord`,
so I can wrap `GamepadButtonType` in a newtype. I suppose serializing
with serde may work or reflect?
# Objective
- Get rid of unwraps in winit fullscreen handling code, which are the
source of some crashes.
- Fix#11275
## Solution
- Replace the unwraps with warnings. Ignore the fullscreen request, do
nothing instead.
# Objective
It would be useful to be able to inspect a `QueryState`'s accesses so we
can detect when the data it accesses changes without having to iterate
it. However there are two things preventing this:
* These accesses are unnecessarily encapsulated.
* `Has<T>` indirectly accesses `T`, but does not register it.
## Solution
* Expose accesses and matches used by `QueryState`.
* Add the notion of "archetypal" accesses, which are not accessed
directly, but whose presence in an archetype affects a query result.

# Objective
I want to keep track of despawned entities.
I am aware of
[`RemovedComponents`](https://docs.rs/bevy/0.12.1/bevy/ecs/prelude/struct.RemovedComponents.html).
However, the docs don't explicitly mention that despawned entities are
also included in this event iterator.
I searched through the bevy tests to find `removal_tracking` in
`crates/bevy_ecs/src/system/mod.rs` that confirmed the behavior:
```rust
...
assert_eq!(
removed_i32.read().collect::<Vec<_>>(),
&[despawned.0],
"despawning causes the correct entity to show up in the 'RemovedComponent' system parameter."
);
...
```
## Solution
- Explicitly mention this behavior in docs.
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.

`bevy_utils` only requires aHash 0.8.3, which is broken on Rust 1.7.6:
```
error: could not compile `ahash` (lib) due to 1 previous error
error[E0635]: unknown feature `stdsimd`
```
See https://github.com/tkaitchuck/aHash/issues/200
This is fixed in aHash 0.8.7, so require at least that version
(Cargo.lock is already up to date).
# 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

> Follow up to #11600 and #10588
@mockersf expressed some [valid
concerns](https://github.com/bevyengine/bevy/pull/11600#issuecomment-1932796498)
about the current system this PR attempts to fix:
The `ComputedTextureSlices` reacts to asset change in both `bevy_sprite`
and `bevy_ui`, meaning that if the `ImageScaleMode` is inserted by
default in the bundles, we will iterate through most 2d items every time
an asset is updated.
# Solution
- `ImageScaleMode` only has two variants: `Sliced` and `Tiled`. I
removed the `Stretched` default
- `ImageScaleMode` is no longer part of any bundle, but the relevant
bundles explain that this additional component can be inserted
This way, the *absence* of `ImageScaleMode` means the image will be
stretched, and its *presence* will include the entity to the various
slicing systems
Optional components in bundles would make this more straigthfoward
# Additional work
Should I add new bundles with the `ImageScaleMode` component ?
# 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.
## Migration Guide

# 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`.

I also added a collection of `fantazy-ui-borders` from
[Kenney's](www.kenney.nl) assets, with the appropriate license (CC).
If it's a problem I can use the same textures as the `sprite_slice`
example
# Work done
Added the `ImageScaleMode` component to the targetted bundles, most of
the logic is directly reused from `bevy_sprite`.
The only additional internal component is the UI specific
`ComputedSlices`, which does the same thing as its spritee equivalent
but adapted to UI code.
Again the slicing is not compatible with `TextureAtlas`, it's something
I need to tackle more deeply in the future
# Fixes
* [x] I noticed that `TextureSlicer::compute_slices` could infinitely
loop if the border was larger that the image half extents, now an error
is triggered and the texture will fallback to being stretched
* [x] I noticed that when using small textures with very small *tiling*
options we could generate hundred of thousands of slices. Now I set a
minimum size of 1 pixel per slice, which is already ridiculously small,
and a warning will be sent at runtime when slice count goes above 1000
* [x] Sprite slicing with `flip_x` or `flip_y` would give incorrect
results, correct flipping is now supported to both sprites and ui image
nodes thanks to @odecay observation
# GPU Alternative
I create a separate branch attempting to implementing 9 slicing and
tiling directly through the `ui.wgsl` fragment shader. It works but
requires sending more data to the GPU:
- slice border
- tiling factors
And more importantly, the actual quad *scale* which is hard to put in
the shader with the current code, so that would be for a later iteration
[`ScheduleLabel`] derive macro uses "ScheduleName" as the trait name by
mistake. This only affects the error message when a user tries to use
the derive macro on a union type. No other code is affected.
# Objective
- This aims to fix#11755
- After #10812 some pipeline compilation can take more time than before
and all call to `get_render_pipeline` should check the result.
## Solution
- Check `get_render_pipeline` call result for msaa_writeback
- I checked that no other call to `get_render_pipeline` in bevy code
base is missng the checking on the result.
Don't try to create a uniform buffer for light probes if there are no
views.
Fixes the panic on examples that have no views, such as
`touch_input_events`.
# Objective

## 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.

# Objective
Bevy could benefit from *irradiance volumes*, also known as *voxel
global illumination* or simply as light probes (though this term is not
preferred, as multiple techniques can be called light probes).
Irradiance volumes are a form of baked global illumination; they work by
sampling the light at the centers of each voxel within a cuboid. At
runtime, the voxels surrounding the fragment center are sampled and
interpolated to produce indirect diffuse illumination.
## Solution
This is divided into two sections. The first is copied and pasted from
the irradiance volume module documentation and describes the technique.
The second part consists of notes on the implementation.
### Overview
An *irradiance volume* is a cuboid voxel region consisting of
regularly-spaced precomputed samples of diffuse indirect light. They're
ideal if you have a dynamic object such as a character that can move
about
static non-moving geometry such as a level in a game, and you want that
dynamic object to be affected by the light bouncing off that static
geometry.
To use irradiance volumes, you need to precompute, or *bake*, the
indirect
light in your scene. Bevy doesn't currently come with a way to do this.
Fortunately, [Blender] provides a [baking tool] as part of the Eevee
renderer, and its irradiance volumes are compatible with those used by
Bevy.
The [`bevy-baked-gi`] project provides a tool, `export-blender-gi`, that
can
extract the baked irradiance volumes from the Blender `.blend` file and
package them up into a `.ktx2` texture for use by the engine. See the
documentation in the `bevy-baked-gi` project for more details as to this
workflow.
Like all light probes in Bevy, irradiance volumes are 1×1×1 cubes that
can
be arbitrarily scaled, rotated, and positioned in a scene with the
[`bevy_transform::components::Transform`] component. The 3D voxel grid
will
be stretched to fill the interior of the cube, and the illumination from
the
irradiance volume will apply to all fragments within that bounding
region.
Bevy's irradiance volumes are based on Valve's [*ambient cubes*] as used
in
*Half-Life 2* ([Mitchell 2006], slide 27). These encode a single color
of
light from the six 3D cardinal directions and blend the sides together
according to the surface normal.
The primary reason for choosing ambient cubes is to match Blender, so
that
its Eevee renderer can be used for baking. However, they also have some
advantages over the common second-order spherical harmonics approach:
ambient cubes don't suffer from ringing artifacts, they are smaller (6
colors for ambient cubes as opposed to 9 for spherical harmonics), and
evaluation is faster. A smaller basis allows for a denser grid of voxels
with the same storage requirements.
If you wish to use a tool other than `export-blender-gi` to produce the
irradiance volumes, you'll need to pack the irradiance volumes in the
following format. The irradiance volume of resolution *(Rx, Ry, Rz)* is
expected to be a 3D texture of dimensions *(Rx, 2Ry, 3Rz)*. The
unnormalized
texture coordinate *(s, t, p)* of the voxel at coordinate *(x, y, z)*
with
side *S* ∈ *{-X, +X, -Y, +Y, -Z, +Z}* is as follows:
```text
s = x
t = y + ⎰ 0 if S ∈ {-X, -Y, -Z}
⎱ Ry if S ∈ {+X, +Y, +Z}
⎧ 0 if S ∈ {-X, +X}
p = z + ⎨ Rz if S ∈ {-Y, +Y}
⎩ 2Rz if S ∈ {-Z, +Z}
```
Visually, in a left-handed coordinate system with Y up, viewed from the
right, the 3D texture looks like a stacked series of voxel grids, one
for
each cube side, in this order:
| **+X** | **+Y** | **+Z** |
| ------ | ------ | ------ |
| **-X** | **-Y** | **-Z** |
A terminology note: Other engines may refer to irradiance volumes as
*voxel
global illumination*, *VXGI*, or simply as *light probes*. Sometimes
*light
probe* refers to what Bevy calls a reflection probe. In Bevy, *light
probe*
is a generic term that encompasses all cuboid bounding regions that
capture
indirect illumination, whether based on voxels or not.
Note that, if binding arrays aren't supported (e.g. on WebGPU or WebGL
2),
then only the closest irradiance volume to the view will be taken into
account during rendering.

### Implementation notes
This patch generalizes light probes so as to reuse as much code as
possible between irradiance volumes and the existing reflection probes.
This approach was chosen because both techniques share numerous
similarities:
1. Both irradiance volumes and reflection probes are cuboid bounding
regions.
2. Both are responsible for providing baked indirect light.
3. Both techniques involve presenting a variable number of textures to
the shader from which indirect light is sampled. (In the current
implementation, this uses binding arrays.)
4. Both irradiance volumes and reflection probes require gathering and
sorting probes by distance on CPU.
5. Both techniques require the GPU to search through a list of bounding
regions.
6. Both will eventually want to have falloff so that we can smoothly
blend as objects enter and exit the probes' influence ranges. (This is
not implemented yet to keep this patch relatively small and reviewable.)
To do this, we generalize most of the methods in the reflection probes
patch #11366 to be generic over a trait, `LightProbeComponent`. This
trait is implemented by both `EnvironmentMapLight` (for reflection
probes) and `IrradianceVolume` (for irradiance volumes). Using a trait
will allow us to add more types of light probes in the future. In
particular, I highly suspect we will want real-time reflection planes
for mirrors in the future, which can be easily slotted into this
framework.
## Changelog
> This section is optional. If this was a trivial fix, or has no
externally-visible impact, you can delete this section.
### Added
* A new `IrradianceVolume` asset type is available for baked voxelized
light probes. You can bake the global illumination using Blender or
another tool of your choice and use it in Bevy to apply indirect
illumination to dynamic objects.
# Objective
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`).

- Adding a deprecated tag on the re-exports, so in future releases these
can be safely removed.
# Objective
During my exploratory work on the remote editor, I found a couple of
types that were either not registered, or that were missing
`ReflectDefault`.
## Solution
- Added registration and `ReflectDefault` where applicable
- (Drive by fix) Moved `Option<f32>` registration to `bevy_core` instead
of `bevy_ui`, along with similar types.

- Fixed: Registered `FogSettings`, `FogFalloff`,
`ParallaxMappingMethod`, `OpaqueRendererMethod` structs for reflection
- Fixed: Registered `ReflectDefault` trait for `ColorGrading` and
`CascadeShadowConfig` structs
# Objective
Includes the UI node size as a parameter to the UiMaterial shader,
useful for SDF-based rendering, aspect ratio correction and other use
cases.
Fixes#11392
## Solution
Added the node size to the UiMaterial vertex shader params and also to
the data that is passed to the fragment shader.

# Objective
- Fixes#11679
## Solution
- Added `IntoSystem::system_type_id` which returns the equivalent of
`system.into_system().type_id()` without construction. This allows for
getting the `TypeId` of functions (a function is an unnamed type and
therefore you cannot call `TypeId::of::<apply_deferred::System>()`)
- Added default implementation of `System::type_id` to ensure
consistency between implementations. Some returned `Self`, while others
were returning an inner value instead. This ensures consistency with
`IntoSystem::system_type_id`.
## Migration Guide
If you use `System::type_id()` on function systems (exclusive or not),
ensure you are comparing its value to other `System::type_id()` calls,
or `IntoSystem::system_type_id()`.
This code wont require any changes, because `IntoSystem`'s are directly
compared to each other.
```rust
fn test_system() {}
let type_id = test_system.type_id();
// ...
// No change required
assert_eq!(test_system.type_id(), type_id);
```
Likewise, this code wont, because `System`'s are directly compared.
```rust
fn test_system() {}
let type_id = IntoSystem::into_system(test_system).type_id();
// ...
// No change required
assert_eq!(IntoSystem::into_system(test_system).type_id(), type_id);
```
The below _does_ require a change, since you're comparing a `System`
type to a `IntoSystem` type.
```rust
fn test_system() {}
// Before
assert_eq!(test_system.type_id(), IntoSystem::into_system(test_system).type_id());
// After
assert_eq!(test_system.system_type_id(), IntoSystem::into_system(test_system).type_id());
```
# Objective
- There are too many `NonSendMarker`
https://docs.rs/bevy/0.12.1/bevy/index.html?search=nonsendmarker
- There should be only one
## Solution
- Use the marker type from bevy_core in bevy_render
---
## Migration Guide
- If you were using `bevy::render::view::NonSendMarker` or
`bevy::render::view:🪟:NonSendMarker`, use
`bevy::core::NonSendMarker` instead
# Objective
Bevy does ridiculous amount of drawcalls, and our batching isn't very
effective because we sort by distance and only batch if we get multiple
of the same object in a row. This can give us slightly better GPU
performance when not using the depth prepass (due to less overdraw), but
ends up being massively CPU bottlenecked due to doing thousands of
unnecessary drawcalls.
## Solution
Change the sort functions to sort by pipeline key then by mesh id for
large performance gains in more realistic scenes than our stress tests.
Pipelines changed:
- Opaque3d
- Opaque3dDeferred
- Opaque3dPrepass
---
## Changelog
- Opaque3d drawing order is now sorted by pipeline and mesh, rather than
by distance. This trades off a bit of GPU time in exchange for massively
better batching in scenes that aren't only drawing huge amounts of a
single object.
# Objective
- Change set of systems as I made a mistake in #11672
- Don't block main when not needed
- Fixes#11235
## Solution
- add a run condition so that the system won't run and block main if not
needed
# Objective
- Some places manually use a `bool` /`AtomicBool` to warn once.
## Solution
- 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
We currently over/underpromise hash stability:
- `HashMap`/`HashSet` use `BuildHasherDefault<AHasher>` instead of
`RandomState`. As a result, the hash is stable within the same run.
- [aHash isn't stable between devices (and
versions)](https://github.com/tkaitchuck/ahash?tab=readme-ov-file#goals-and-non-goals),
yet it's used for `StableHashMap`/`StableHashSet`
- the specialized hashmaps are stable
Interestingly, `StableHashMap`/`StableHashSet` aren't used by Bevy
itself (anymore).
## Solution
Add/fix documentation
## Alternatives
For `StableHashMap`/`StableHashSet`:
- remove them
- revive #7107
---
## Changelog
- added iteration stability guarantees for different hashmaps
This is just a minor fix extracted from #11697
A logic error. We tried to close the polygon shape, if the user
specifies an
unclosed polygon. The closing linestring previously didn't close the
polygon
though, but instead added a zero length line at the last coordinate.

the `&str` to a `String`. Which is wasteful.
## Solution
I made `DynamicStruct::insert_boxed` take in a `impl Into<Cow<str>>`.
Same for `DynamicStruct::insert`.
---
## Changelog
- `DynamicStruct::insert_boxed` and `DynamicStruct::insert` now support
taking in anything that implements `impl Into<Cow<str>>`.
# Objective
Send `SceneInstanceReady` only once per scene.
## Solution
I assume that this was not intentional.
So I just changed it to only be sent once per scene.
---
## Changelog
### Fixed
- Fixed `SceneInstanceReady` being emitted for every `Entity` in a
scene.
# 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 #4188, make users could set application ID for bevy apps.
## Solution
- Add `name` field to `bevy:🪟:Window`. Specifying this field adds
different properties to the window: application ID on `Wayland`,
`WM_CLASS` on `X11`, or window class name on Windows. It has no effect
on other platforms.
---
## Changelog
### Added
- Add `name` to `bevy:🪟:Window`.
## Migration Guide
- Set the `bevy_window::Window`'s `name` field when needed:
```rust
App::new()
.add_plugins(DefaultPlugins.set(WindowPlugin {
primary_window: Some(Window {
title: "I am a window!".into(),
name: Some("SpaceGameCompany.SpaceShooter".into()),
..default()
}),
..default()
}))
.run();
```

# 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.

# Objective
- (Partially) Fixes#9904
- Acts on #9910
## Solution
- Deprecated the relevant methods from `Query`, cascading changes as
required across Bevy.
---
## Changelog
- Deprecated `QueryState::get_component_unchecked_mut` method
- Deprecated `Query::get_component` method
- Deprecated `Query::get_component_mut` method
- Deprecated `Query::component` method
- Deprecated `Query::component_mut` method
- Deprecated `Query::get_component_unchecked_mut` method
## Migration Guide
### `QueryState::get_component_unchecked_mut`
Use `QueryState::get_unchecked_manual` and select for the exact
component based on the structure of the exact query as required.
### `Query::(get_)component(_unchecked)(_mut)`
Use `Query::get` and select for the exact component based on the
structure of the exact query as required.
- For mutable access (`_mut`), use `Query::get_mut`
- For unchecked access (`_unchecked`), use `Query::get_unchecked`
- For panic variants (non-`get_`), add `.unwrap()`
## Notes
- `QueryComponentError` can be removed once these deprecated methods are
also removed. Due to an interaction with `thiserror`'s derive macro, it
is not marked as deprecated.
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
- Update `tracing-tracy`.
- Closes#11598.
## Solution
- Bump `tracing-tracy` to 0.11.0 and `tracy-client` alongside it to
0.17.0 to avoid duplicating that dependency in the deps tree.
- `TracyLayer` is now configurable on creation, so use the default
config.

# 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
Add interactive system debugging capabilities to bevy, providing
step/break/continue style capabilities to running system schedules.
* Original implementation: #8063
- `ignore_stepping()` everywhere was too much complexity
* Schedule-config & Resource discussion: #8168
- Decided on selective adding of Schedules & Resource-based control
## Solution
Created `Stepping` Resource. This resource can be used to enable
stepping on a per-schedule basis. Systems within schedules can be
individually configured to:
* AlwaysRun: Ignore any stepping state and run every frame
* NeverRun: Never run while stepping is enabled
- this allows for disabling of systems while debugging
* Break: If we're running the full frame, stop before this system is run
Stepping provides two modes of execution that reflect traditional
debuggers:
* Step-based: Only execute one system at a time
* Continue/Break: Run all systems, but stop before running a system
marked as Break
### Demo
https://user-images.githubusercontent.com/857742/233630981-99f3bbda-9ca6-4cc4-a00f-171c4946dc47.mov
Breakout has been modified to use Stepping. The game runs normally for a
couple of seconds, then stepping is enabled and the game appears to
pause. A list of Schedules & Systems appears with a cursor at the first
System in the list. The demo then steps forward full frames using the
spacebar until the ball is about to hit a brick. Then we step system by
system as the ball impacts a brick, showing the cursor moving through
the individual systems. Finally the demo switches back to frame stepping
as the ball changes course.
### Limitations
Due to architectural constraints in bevy, there are some cases systems
stepping will not function as a user would expect.
#### Event-driven systems
Stepping does not support systems that are driven by `Event`s as events
are flushed after 1-2 frames. Although game systems are not running
while stepping, ignored systems are still running every frame, so events
will be flushed.
This presents to the user as stepping the event-driven system never
executes the system. It does execute, but the events have already been
flushed.
This can be resolved by changing event handling to use a buffer for
events, and only dropping an event once all readers have read it.
The work-around to allow these systems to properly execute during
stepping is to have them ignore stepping:
`app.add_systems(event_driven_system.ignore_stepping())`. This was done
in the breakout example to ensure sound played even while stepping.
#### Conditional Systems
When a system is stepped, it is given an opportunity to run. If the
conditions of the system say it should not run, it will not.
Similar to Event-driven systems, if a system is conditional, and that
condition is only true for a very small time window, then stepping the
system may not execute the system. This includes depending on any sort
of external clock.
This exhibits to the user as the system not always running when it is
stepped.
A solution to this limitation is to ensure any conditions are consistent
while stepping is enabled. For example, all systems that modify any
state the condition uses should also enable stepping.
#### State-transition Systems
Stepping is configured on the per-`Schedule` level, requiring the user
to have a `ScheduleLabel`.
To support state-transition systems, bevy generates needed schedules
dynamically. Currently it’s very difficult (if not impossible, I haven’t
verified) for the user to get the labels for these schedules.
Without ready access to the dynamically generated schedules, and a
resolution for the `Event` lifetime, **stepping of the state-transition
systems is not supported**
---
## Changelog
- `Schedule::run()` updated to consult `Stepping` Resource to determine
which Systems to run each frame
- Added `Schedule.label` as a `BoxedSystemLabel`, along with supporting
`Schedule::set_label()` and `Schedule::label()` methods
- `Stepping` needed to know which `Schedule` was running, and prior to
this PR, `Schedule` didn't track its own label
- Would have preferred to add `Schedule::with_label()` and remove
`Schedule::new()`, but this PR touches enough already
- Added calls to `Schedule.set_label()` to `App` and `World` as needed
- Added `Stepping` resource
- Added `Stepping::begin_frame()` system to `MainSchedulePlugin`
- Run before `Main::run_main()`
- Notifies any `Stepping` Resource a new render frame is starting
## Migration Guide
- Add a call to `Schedule::set_label()` for any custom `Schedule`
- This is only required if the `Schedule` will be stepped

# 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
Allow animation of types other than translation, scale, and rotation on
`Transforms`.
## Solution
Add a base trait for all values that can be animated by the animation
system. This provides the basic operations for sampling and blending
animation values for more than just translation, rotation, and scale.
This implements part of bevyengine/rfcs#51, but is missing the
implementations for `Range<T>` and `Color`. This also does not fully
integrate with the existing `AnimationPlayer` yet, just setting up the
trait.

# Objective
Fix an issue where events are not being dropped after being read. I
believe #10077 introduced this issue. The code currently works as
follows:
1. `EventUpdateSignal` is **shared for all event types**
2. During the fixed update phase, `EventUpdateSignal` is set to true
3. `event_update_system`, **unique per event type**, runs to update
Events<T>
4. `event_update_system` reads value of `EventUpdateSignal` to check if
it should update, and then **resets** the value to false
If there are multiple event types, the first `event_update_system` run
will reset the shared `EventUpdateSignal` signal, preventing other
events from being cleared.
## Solution
I've updated the code to have separate signals per event type and added
a shared signal to notify all systems that the time plugin is installed.
## Changelog
- Fixed bug where events were not being dropped
The PR is in a reviewable state now in the sense that the basic
implementations are there. There are still some ToDos that I'm aware of:
- [x] docs for all the new structs and traits
- [x] implement `Default` and derive other useful traits for the new
structs
- [x] Take a look at the notes again (Do this after a first round of
reviews)
- [x] Take care of the repetition in the circle drawing functions
---
# Objective
- TLDR: This PR enables us to quickly draw all the newly added
primitives from `bevy_math` in immediate mode with gizmos
- Addresses #10571
## Solution
- This implements the first design idea I had that covered everything
that was mentioned in the Issue
https://github.com/bevyengine/bevy/issues/10571#issuecomment-1863646197
---
## Caveats
- I added the `Primitive(2/3)d` impls for `Direction(2/3)d` to make them
work with the current solution. We could impose less strict requirements
for the gizmoable objects and remove the impls afterwards if the
community doesn't like the current approach.
---
## Changelog
- implement capabilities to draw ellipses on the gizmo in general (this
was required to have some code which is able to draw the ellipse
primitive)
- refactored circle drawing code to use the more general ellipse drawing
code to keep code duplication low
- implement `Primitive2d` for `Direction2d` and impl `Primitive3d` for
`Direction3d`
- implement trait to draw primitives with specialized details with
gizmos
- `GizmoPrimitive2d` for all the 2D primitives
- `GizmoPrimitive3d` for all the 3D primitives
- (question while writing this: Does it actually matter if we split this
in 2D and 3D? I guess it could be useful in the future if we do
something based on the main rendering mode even though atm it's kinda
useless)

# Objective
Glyph positions don't account for padding added to the font texture
atlas, resulting in them being off by one physical pixel in both axis.
## Example
```rust
use bevy::{
prelude::*, window::WindowResolution
};
fn main() {
App::new()
.add_plugins(DefaultPlugins.set(WindowPlugin {
primary_window: Some(Window {
resolution: WindowResolution::default().with_scale_factor_override(1.),

The coordinates are off by one in physical coordinates, not logical. So
the difference only becomes obvious with `UiScale` and the window scale
factor set to low values.
## Solution
Translate glyph positions by -1 in both axes.

# Objective
Drawing a `Gizmos::circle` whose normal is derived from a Transform's
local axes now requires converting a Vec3 to a Direction3d and
unwrapping the result, and I think we shold move the conversion into
Bevy.
## Solution
We can make
`Transform::{left,right,up,down,forward,back,local_x,local_y,local_z}`
return a Direction3d, because they know that their results will be of
finite non-zero length (roughly 1.0).
---
## Changelog
`Transform::up()` and similar functions now return `Direction3d` instead
of `Vec3`.
## Migration Guide
Callers of `Transform::up()` and similar functions may have to
dereference the returned `Direction3d` to get to the inner `Vec3`.
