# 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:
https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md

# Objective
- Prep for https://github.com/bevyengine/bevy/pull/10164
- Make deferred_lighting_pass_id a ColorAttachment
- Correctly extract shadow view frusta so that the view uniforms get
populated
- Make some needed things public
- Misc formatting
# Objective
Keep up to date with wgpu.
## Solution
Update the wgpu version.
Currently blocked on naga_oil updating to naga 0.14 and releasing a new
version.
3d scenes (or maybe any scene with lighting?) currently don't render
anything due to
```
error: naga_oil bug, please file a report: composer failed to build a valid header: Type [2] '' is invalid
= Capability Capabilities(CUBE_ARRAY_TEXTURES) is required
```
I'm not sure what should be passed in for `wgpu::InstanceFlags`, or if we want to make the gles3minorversion configurable (might be useful for debugging?)
Currently blocked on https://github.com/bevyengine/naga_oil/pull/63, and https://github.com/gfx-rs/wgpu/issues/4569 to be fixed upstream in wgpu first.
## Known issues
Amd+windows+vulkan has issues with texture_binding_arrays (see the image [here](https://github.com/bevyengine/bevy/pull/10266#issuecomment-1819946278)), but that'll be fixed in the next wgpu/naga version, and you can just use dx12 as a workaround for now (Amd+linux mesa+vulkan texture_binding_arrays are fixed though).
---
## Changelog
Updated wgpu to 0.18, naga to 0.14.2, and naga_oil to 0.11.
- Windows desktop GL should now be less painful as it no longer requires Angle.
- You can now toggle shader validation and debug information for debug and release builds using `WgpuSettings.instance_flags` and [InstanceFlags](https://docs.rs/wgpu/0.18.0/wgpu/struct.InstanceFlags.html)
## Migration Guide
- `RenderPassDescriptor` `color_attachments` (as well as `RenderPassColorAttachment`, and `RenderPassDepthStencilAttachment`) now use `StoreOp::Store` or `StoreOp::Discard` instead of a `boolean` to declare whether or not they should be stored.
- `RenderPassDescriptor` now have `timestamp_writes` and `occlusion_query_set` fields. These can safely be set to `None`.
- `ComputePassDescriptor` now have a `timestamp_writes` field. This can be set to `None` for now.
- See the [wgpu changelog](https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md#v0180-2023-10-25) for additional details
# Objective
- Follow up to #9694
## Solution
- Same api as #9694 but adapted for `BindGroupLayoutEntry`
- Use the same `ShaderStages` visibilty for all entries by default
- Add `BindingType` helper function that mirror the wgsl equivalent and
that make writing layouts much simpler.
Before:
```rust
let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor {
label: Some("post_process_bind_group_layout"),
entries: &[
BindGroupLayoutEntry {
binding: 0,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Texture {
sample_type: TextureSampleType::Float { filterable: true },
view_dimension: TextureViewDimension::D2,
multisampled: false,
},
count: None,
},
BindGroupLayoutEntry {
binding: 1,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Sampler(SamplerBindingType::Filtering),
count: None,
},
BindGroupLayoutEntry {
binding: 2,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Buffer {
ty: bevy::render::render_resource::BufferBindingType::Uniform,
has_dynamic_offset: false,
min_binding_size: Some(PostProcessSettings::min_size()),
},
count: None,
},
],
});
```
After:
```rust
let layout = render_device.create_bind_group_layout(
"post_process_bind_group_layout"),
&BindGroupLayoutEntries::sequential(
ShaderStages::FRAGMENT,
(
texture_2d_f32(),
sampler(SamplerBindingType::Filtering),
uniform_buffer(false, Some(PostProcessSettings::min_size())),
),
),
);
```
Here's a more extreme example in bevy_solari:
86dab7f5da
---
## Changelog
- Added `BindGroupLayoutEntries` and all `BindingType` helper functions.
## Migration Guide
`RenderDevice::create_bind_group_layout()` doesn't take a
`BindGroupLayoutDescriptor` anymore. You need to provide the parameters
separately
```rust
// 0.12
let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor {
label: Some("post_process_bind_group_layout"),
entries: &[
BindGroupLayoutEntry {
// ...
},
],
});
// 0.13
let layout = render_device.create_bind_group_layout(
"post_process_bind_group_layout",
&[
BindGroupLayoutEntry {
// ...
},
],
);
```
## TODO
- [x] implement a `Dynamic` variant
- [x] update the `RenderDevice::create_bind_group_layout()` api to match
the one from `RenderDevice::creat_bind_group()`
- [x] docs
# Objective
The `map_async` method involves a type `BufferAsyncError`:
https://docs.rs/bevy/latest/bevy/render/render_resource/struct.BufferSlice.html#method.map_async
This type is not re-exported in Bevy, so if a user wants to store a
struct involving this type they have to add wgpu manually to their
manifest.
## Solution
- Re-export wgpu::BufferAsyncError
---
## Changelog
### Added
- Re-export wgpu::BufferAsyncError
Signed-off-by: Torstein Grindvik <torstein.grindvik@muybridge.com>
Co-authored-by: Torstein Grindvik <torstein.grindvik@muybridge.com>
# Objective
Calling `RenderDevice::poll` requires an instance of `wgpu::Maintain`,
but the type was not reexported by bevy. Working around it requires
adding a dependency on `wgpu`, since bevy does not reexport the `wgpu`
crate as a whole anywhere.
## Solution
Reexport `wgpu::Maintain` in `render_resource`, where the other wgpu
types are reexported.
# Objective
Simplify bind group creation code. alternative to (and based on) #9476
## Solution
- Add a `BindGroupEntries` struct that can transparently be used where
`&[BindGroupEntry<'b>]` is required in BindGroupDescriptors.
Allows constructing the descriptor's entries as:
```rust
render_device.create_bind_group(
"my_bind_group",
&my_layout,
&BindGroupEntries::with_indexes((
(2, &my_sampler),
(3, my_uniform),
)),
);
```
instead of
```rust
render_device.create_bind_group(
"my_bind_group",
&my_layout,
&[
BindGroupEntry {
binding: 2,
resource: BindingResource::Sampler(&my_sampler),
},
BindGroupEntry {
binding: 3,
resource: my_uniform,
},
],
);
```
or
```rust
render_device.create_bind_group(
"my_bind_group",
&my_layout,
&BindGroupEntries::sequential((&my_sampler, my_uniform)),
);
```
instead of
```rust
render_device.create_bind_group(
"my_bind_group",
&my_layout,
&[
BindGroupEntry {
binding: 0,
resource: BindingResource::Sampler(&my_sampler),
},
BindGroupEntry {
binding: 1,
resource: my_uniform,
},
],
);
```
the structs has no user facing macros, is tuple-type-based so stack
allocated, and has no noticeable impact on compile time.
- Also adds a `DynamicBindGroupEntries` struct with a similar api that
uses a `Vec` under the hood and allows extending the entries.
- Modifies `RenderDevice::create_bind_group` to take separate arguments
`label`, `layout` and `entries` instead of a `BindGroupDescriptor`
struct. The struct can't be stored due to the internal references, and
with only 3 members arguably does not add enough context to justify
itself.
- Modify the codebase to use the new api and the `BindGroupEntries` /
`DynamicBindGroupEntries` structs where appropriate (whenever the
entries slice contains more than 1 member).
## Migration Guide
- Calls to `RenderDevice::create_bind_group({BindGroupDescriptor {
label, layout, entries })` must be amended to
`RenderDevice::create_bind_group(label, layout, entries)`.
- If `label`s have been specified as `"bind_group_name".into()`, they
need to change to just `"bind_group_name"`. `Some("bind_group_name")`
and `None` will still work, but `Some("bind_group_name")` can optionally
be simplified to just `"bind_group_name"`.

# Objective
- Add a type for uploading a Rust `Vec<T>` to a GPU `array<T>`.
- Makes progress towards https://github.com/bevyengine/bevy/issues/89.
## Solution
- Port @superdump's `BatchedUniformBuffer` to bevy main, as a fallback
for WebGL2, which doesn't support storage buffers.
- Rather than getting an `array<T>` in a shader, you get an `array<T,
N>`, and have to rebind every N elements via dynamic offsets.
- Add `GpuArrayBuffer` to abstract over
`StorageBuffer<Vec<T>>`/`BatchedUniformBuffer`.
## Future Work
Add a shader macro kinda thing to abstract over the following
automatically:
https://github.com/bevyengine/bevy/pull/8204#pullrequestreview-1396911727
---
## Changelog
* Added `GpuArrayBuffer`, `GpuComponentArrayBufferPlugin`,
`GpuArrayBufferable`, and `GpuArrayBufferIndex` types.
* Added `DynamicUniformBuffer::new_with_alignment()`.

# Objective
Allow for creating pipelines that use push constants. To be able to use push constants. Fixes#4825
As of right now, trying to call `RenderPass::set_push_constants` will trigger the following error:
```
thread 'main' panicked at 'wgpu error: Validation Error
Caused by:
In a RenderPass
note: encoder = `<CommandBuffer-(0, 59, Vulkan)>`
In a set_push_constant command
provided push constant is for stage(s) VERTEX | FRAGMENT | VERTEX_FRAGMENT, however the pipeline layout has no push constant range for the stage(s) VERTEX | FRAGMENT | VERTEX_FRAGMENT
```
## Solution
Add a field push_constant_ranges to` RenderPipelineDescriptor` and `ComputePipelineDescriptor`.
This PR supersedes #4908 which now contains merge conflicts due to significant changes to `bevy_render`.
Meanwhile, this PR also made the `layout` field of `RenderPipelineDescriptor` and `ComputePipelineDescriptor` non-optional. If the user do not need to specify the bind group layouts, they can simply supply an empty vector here. No need for it to be optional.
---
## Changelog
- Add a field push_constant_ranges to RenderPipelineDescriptor and ComputePipelineDescriptor
- Made the `layout` field of RenderPipelineDescriptor and ComputePipelineDescriptor non-optional.
## Migration Guide
- Add push_constant_ranges: Vec::new() to every `RenderPipelineDescriptor` and `ComputePipelineDescriptor`
- Unwrap the optional values on the `layout` field of `RenderPipelineDescriptor` and `ComputePipelineDescriptor`. If the descriptor has no layout, supply an empty vector.

Removed `const_vec2`/`const_vec3`
and replaced with equivalent `.from_array`.
# Objective
Fixes#5112
## Solution
- `encase` needs to update to `glam` as well. See teoxoy/encase#4 on progress on that.
- `hexasphere` also needs to be updated, see OptimisticPeach/hexasphere#12.
# Objective
- Fixes#3970
- To support Bevy's shader abstraction(shader defs, shader imports and hot shader reloading) for compute shaders, I have followed carts advice and change the `PipelinenCache` to accommodate both compute and render pipelines.
## Solution
- renamed `RenderPipelineCache` to `PipelineCache`
- Cached Pipelines are now represented by an enum (render, compute)
- split the `SpecializedPipelines` into `SpecializedRenderPipelines` and `SpecializedComputePipelines`
- updated the game of life example
## Open Questions
- should `SpecializedRenderPipelines` and `SpecializedComputePipelines` be merged and how would we do that?
- should the `get_render_pipeline` and `get_compute_pipeline` methods be merged?
- is pipeline specialization for different entry points a good pattern

# Objective
- Add a helper for storage buffers similar to `UniformVec`
## Solution
- Add a `StorageBuffer<T, U>` where `T` is the main body of the shader struct without any final variable-sized array member, and `U` is the type of the items in a variable-sized array.
- Use `()` as the type for unwanted parts, e.g. `StorageBuffer<(), Vec4>::default()` would construct a binding that would work with `struct MyType { data: array<vec4<f32>>; }` in WGSL and `StorageBuffer<MyType, ()>::default()` would work with `struct MyType { ... }` in WGSL as long as there are no variable-sized arrays.
- Std430 requires that there is at most one variable-sized array in a storage buffer, that if there is one it is the last member of the binding, and that it has at least one item. `StorageBuffer` handles all of these constraints.
# Objective
- `WgpuOptions` is mutated to be updated with the actual device limits and features, but this information is readily available to both the main and render worlds through the `RenderDevice` which has .limits() and .features() methods
- Information about the adapter in terms of its name, the backend in use, etc were not being exposed but have clear use cases for being used to take decisions about what rendering code to use. For example, if something works well on AMD GPUs but poorly on Intel GPUs. Or perhaps something works well in Vulkan but poorly in DX12.
## Solution
- Stop mutating `WgpuOptions `and don't insert the updated values into the main and render worlds
- Return `AdapterInfo` from `initialize_renderer` and insert it into the main and render worlds
- Use `RenderDevice` limits in the lighting code that was using `WgpuOptions.limits`.
- Renamed `WgpuOptions` to `WgpuSettings`
# Objective
In order to create a glsl shader, we must provide the `naga::ShaderStage` type which is not exported by bevy, meaning a user would have to manually include naga just to access this type.
`pub fn from_glsl(source: impl Into<Cow<'static, str>>, stage: naga::ShaderStage) -> Shader {`
## Solution
Re-rexport naga::ShaderStage from `render_resources`
# Objective
- I want to port `bevy_egui` to Bevy main and only reuse re-exports from Bevy
## Solution
- Add exports for `BufferBinding` and `BufferDescriptor`

# Objective
- Our crevice is still called "crevice", which we can't use for a release
- Users would need to use our "crevice" directly to be able to use the derive macro
## Solution
- Rename crevice to bevy_crevice, and crevice-derive to bevy-crevice-derive
- Re-export it from bevy_render, and use it from bevy_render everywhere
- Fix derive macro to work either from bevy_render, from bevy_crevice, or from bevy
## Remaining
- It is currently re-exported as `bevy::render::bevy_crevice`, is it the path we want?
- After a brief suggestion to Cart, I changed the version to follow Bevy version instead of crevice, do we want that?
- Crevice README.md need to be updated
- in the `Cargo.toml`, there are a few things to change. How do we want to change them? How do we keep attributions to original Crevice?

# Objective
- Only bevy_render should depend directly on wgpu
- This helps to make sure bevy_render re-exports everything needed from wgpu

This makes the [New Bevy Renderer](#2535) the default (and only) renderer. The new renderer isn't _quite_ ready for the final release yet, but I want as many people as possible to start testing it so we can identify bugs and address feedback prior to release.
The examples are all ported over and operational with a few exceptions:
* I removed a good portion of the examples in the `shader` folder. We still have some work to do in order to make these examples possible / ergonomic / worthwhile: #3120 and "high level shader material plugins" are the big ones. This is a temporary measure.
* Temporarily removed the multiple_windows example: doing this properly in the new renderer will require the upcoming "render targets" changes. Same goes for the render_to_texture example.
* Removed z_sort_debug: entity visibility sort info is no longer available in app logic. we could do this on the "render app" side, but i dont consider it a priority.
