Relicense Bevy under the dual MIT or Apache-2.0 license (#2509) This relicenses Bevy under the dual MIT or Apache-2.0 license. For rationale, see #2373. * Changes the LICENSE file to describe the dual license. Moved the MIT license to docs/LICENSE-MIT. Added the Apache-2.0 license to docs/LICENSE-APACHE. I opted for this approach over dumping both license files at the root (the more common approach) for a number of reasons: * Github links to the "first" license file (LICENSE-APACHE) in its license links (you can see this in the wgpu and rust-analyzer repos). People clicking these links might erroneously think that the apache license is the only option. Rust and Amethyst both use COPYRIGHT or COPYING files to solve this problem, but this creates more file noise (if you do everything at the root) and the naming feels way less intuitive. * People have a reflex to look for a LICENSE file. By providing a single license file at the root, we make it easy for them to understand our licensing approach. * I like keeping the root clean and noise free * There is precedent for putting the apache and mit license text in sub folders (amethyst) * Removed the `Copyright (c) 2020 Carter Anderson` copyright notice from the MIT license. I don't care about this attribution, it might make license compliance more difficult in some cases, and it didn't properly attribute other contributors. We shoudn't replace it with something like "Copyright (c) 2021 Bevy Contributors" because "Bevy Contributors" is not a legal entity. Instead, we just won't include the copyright line (which has precedent ... Rust also uses this approach). * Updates crates to use the new "MIT OR Apache-2.0" license value * Removes the old legion-transform license file from bevy_transform. bevy_transform has been its own, fully custom implementation for a long time and that license no longer applies. * Added a License section to the main readme * Updated our Bevy Plugin licensing guidelines. As a follow-up we should update the website to properly describe the new license. Closes #2373

Visibilty Inheritance, universal ComputedVisibility and RenderLayers support (#5310) # Objective Fixes #4907. Fixes #838. Fixes #5089. Supersedes #5146. Supersedes #2087. Supersedes #865. Supersedes #5114 Visibility is currently entirely local. Set a parent entity to be invisible, and the children are still visible. This makes it hard for users to hide entire hierarchies of entities. Additionally, the semantics of `Visibility` vs `ComputedVisibility` are inconsistent across entity types. 3D meshes use `ComputedVisibility` as the "definitive" visibility component, with `Visibility` being just one data source. Sprites just use `Visibility`, which means they can't feed off of `ComputedVisibility` data, such as culling information, RenderLayers, and (added in this pr) visibility inheritance information. ## Solution Splits `ComputedVisibilty::is_visible` into `ComputedVisibilty::is_visible_in_view` and `ComputedVisibilty::is_visible_in_hierarchy`. For each visible entity, `is_visible_in_hierarchy` is computed by propagating visibility down the hierarchy. The `ComputedVisibility::is_visible()` function combines these two booleans for the canonical "is this entity visible" function. Additionally, all entities that have `Visibility` now also have `ComputedVisibility`. Sprites, Lights, and UI entities now use `ComputedVisibility` when appropriate. This means that in addition to visibility inheritance, everything using Visibility now also supports RenderLayers. Notably, Sprites (and other 2d objects) now support `RenderLayers` and work properly across multiple views. Also note that this does increase the amount of work done per sprite. Bevymark with 100,000 sprites on `main` runs in `0.017612` seconds and this runs in `0.01902`. That is certainly a gap, but I believe the api consistency and extra functionality this buys us is worth it. See [this thread](https://github.com/bevyengine/bevy/pull/5146#issuecomment-1182783452) for more info. Note that #5146 in combination with #5114 _are_ a viable alternative to this PR and _would_ perform better, but that comes at the cost of api inconsistencies and doing visibility calculations in the "wrong" place. The current visibility system does have potential for performance improvements. I would prefer to evolve that one system as a whole rather than doing custom hacks / different behaviors for each feature slice. Here is a "split screen" example where the left camera uses RenderLayers to filter out the blue sprite. ![image](https://user-images.githubusercontent.com/2694663/178814868-2e9a2173-bf8c-4c79-8815-633899d492c3.png) Note that this builds directly on #5146 and that @james7132 deserves the credit for the baseline visibility inheritance work. This pr moves the inherited visibility field into `ComputedVisibility`, then does the additional work of porting everything to `ComputedVisibility`. See my [comments here](https://github.com/bevyengine/bevy/pull/5146#issuecomment-1182783452) for rationale. ## Follow up work * Now that lights use ComputedVisibility, VisibleEntities now includes "visible lights" in the entity list. Functionally not a problem as we use queries to filter the list down in the desired context. But we should consider splitting this out into a separate`VisibleLights` collection for both clarity and performance reasons. And _maybe_ even consider scoping `VisibleEntities` down to `VisibleMeshes`?. * Investigate alternative sprite rendering impls (in combination with visibility system tweaks) that avoid re-generating a per-view fixedbitset of visible entities every frame, then checking each ExtractedEntity. This is where most of the performance overhead lives. Ex: we could generate ExtractedEntities per-view using the VisibleEntities list, avoiding the need for the bitset. * Should ComputedVisibility use bitflags under the hood? This would cut down on the size of the component, potentially speed up the `is_visible()` function, and allow us to cheaply expand ComputedVisibility with more data (ex: split out local visibility and parent visibility, add more culling classes, etc). --- ## Changelog * ComputedVisibility now takes hierarchy visibility into account. * 2D, UI and Light entities now use the ComputedVisibility component. ## Migration Guide If you were previously reading `Visibility::is_visible` as the "actual visibility" for sprites or lights, use `ComputedVisibilty::is_visible()` instead: ```rust // before (0.7) fn system(query: Query<&Visibility>) { for visibility in query.iter() { if visibility.is_visible { log!("found visible entity"); } } } // after (0.8) fn system(query: Query<&ComputedVisibility>) { for visibility in query.iter() { if visibility.is_visible() { log!("found visible entity"); } } } ``` Co-authored-by: Carter Anderson <mcanders1@gmail.com>

Use radsort for Transparent2d PhaseItem sorting (#9882) # Objective Fix a performance regression in the "[bevy vs pixi](https://github.com/SUPERCILEX/bevy-vs-pixi)" benchmark. This benchmark seems to have a slightly pathological distribution of `z` values -- Sprites are spawned with a random `z` value with a child sprite at `f32::EPSILON` relative to the parent. See discussion here: https://github.com/bevyengine/bevy/issues/8100#issuecomment-1726978633 ## Solution Use `radsort` for sorting `Transparent2d` `PhaseItem`s. Use random `z` values in bevymark to stress the phase sort. Add an `--ordered-z` option to `bevymark` that uses the old behavior. ## Benchmarks mac m1 max | benchmark | fps before | fps after | diff | | - | - | - | - | | bevymark --waves 120 --per-wave 1000 --random-z | 42.16 | 47.06 | 🟩 +11.6% | | bevymark --waves 120 --per-wave 1000 | 52.50 | 52.29 | 🟥 -0.4% | | bevymark --waves 120 --per-wave 1000 --mode mesh2d --random-z | 9.64 | 10.24 | 🟩 +6.2% | | bevymark --waves 120 --per-wave 1000 --mode mesh2d | 15.83 | 15.59 | 🟥 -1.5% | | bevy-vs-pixi | 39.71 | 59.88 | 🟩 +50.1% | ## Discussion It's possible that `TransparentUi` should also change. We could probably use `slice::sort_unstable_by_key` with the current sort key though, as its items are always sorted and unique. I'd prefer to follow up later to look into that. Here's a survey of sorts used by other `PhaseItem`s #### slice::sort_by_key `Transparent2d`, `TransparentUi` #### radsort `Opaque3d`, `AlphaMask3d`, `Transparent3d`, `Opaque3dPrepass`, `AlphaMask3dPrepass`, `Shadow` I also tried `slice::sort_unstable_by_key` with a compound sort key including `Entity`, but it didn't seem as promising and I didn't test it as thoroughly. --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: Robert Swain <robert.swain@gmail.com>
