update shader imports (#10180) # Objective - bump naga_oil to 0.10 - update shader imports to use rusty syntax ## Migration Guide naga_oil 0.10 reworks the import mechanism to support more syntax to make it more rusty, and test for item use before importing to determine which imports are modules and which are items, which allows: - use rust-style imports ``` #import bevy_pbr::{ pbr_functions::{alpha_discard as discard, apply_pbr_lighting}, mesh_bindings, } ``` - import partial paths: ``` #import part::of::path ... path::remainder::function(); ``` which will call to `part::of::path::remainder::function` - use fully qualified paths without importing: ``` // #import bevy_pbr::pbr_functions bevy_pbr::pbr_functions::pbr() ``` - use imported items without qualifying ``` #import bevy_pbr::pbr_functions::pbr // for backwards compatibility the old style is still supported: // #import bevy_pbr::pbr_functions pbr ... pbr() ``` - allows most imported items to end with `_` and numbers (naga_oil#30). still doesn't allow struct members to end with `_` or numbers but it's progress. - the vast majority of existing shader code will work without changes, but will emit "deprecated" warnings for old-style imports. these can be suppressed with the `allow-deprecated` feature. - partly breaks overrides (as far as i'm aware nobody uses these yet) - now overrides will only be applied if the overriding module is added as an additional import in the arguments to `Composer::make_naga_module` or `Composer::add_composable_module`. this is necessary to support determining whether imports are modules or items. 2023-10-21 11:51:58 +00:00			`#import bevy_pbr::forward_io::VertexOutput`

Configurable colors for wireframe (#5303) # Objective - Make the wireframe colors configurable at the global level and the single mesh level - Based on https://github.com/bevyengine/bevy/pull/5314 This video shows what happens when playing with various settings from the example https://github.com/bevyengine/bevy/assets/8348954/1ee9aee0-fab7-4da8-bc5d-8d0562bb34e6 ## Solution - Add a `color` field to the `WireframeMaterial` - Use a `WireframeColor` component to configure the color per entity - Add a `default_color` field to `WireframeConfig` for global wireframes or wireframes with no specified color. ## Notes - Most of the docs and the general idea for `WireframeColor` came from [UberLambda](https://github.com/UberLambda) in #3677 but the code ended up completely different so I created a separate branch. ~~I'm not sure how to correctly credit them on this PR.~~ (I re-created the commit but I added them as co-author in the commit message) ~~Closes https://github.com/bevyengine/bevy/pull/3677~~ ~~Closes https://github.com/bevyengine/bevy/pull/5301~~ ~~https://github.com/bevyengine/bevy/pull/5314 should be merged before this PR.~~ 2023-10-13 00:06:24 +00:00			`struct WireframeMaterial {`

update wireframe rendering to new renderer (#3193) Updates the wireframe rendering initialliy implemented in https://github.com/bevyengine/bevy/pull/562 to the new renderer. It lives in `bevy_pbr2` instead of `bevy_render2` because that way it can reuse the `MeshPipeline`. 2021-12-10 21:09:36 +00:00

update wgpu to 0.13 (#5168) # Objective - Update wgpu to 0.13 - ~~Wait, is wgpu 0.13 released? No, but I had most of the changes already ready since playing with webgpu~~ well it has been released now - Also update parking_lot to 0.12 and naga to 0.9 ## Solution - Update syntax for wgsl shaders https://github.com/gfx-rs/wgpu/blob/master/CHANGELOG.md#wgsl-syntax - Add a few options, remove some references: https://github.com/gfx-rs/wgpu/blob/master/CHANGELOG.md#other-breaking-changes - fragment inputs should now exactly match vertex outputs for locations, so I added exports for those to be able to reuse them https://github.com/gfx-rs/wgpu/pull/2704 2022-07-14 21:17:16 +00:00			`@fragment`
pbr shader cleanup (#10105) # Objective cleanup some pbr shader code. improve shader stage io consistency and make pbr.wgsl (probably many people's first foray into bevy shader code) a little more human-readable. also fix a couple of small issues with deferred rendering. ## Solution mesh_vertex_output: - rename to forward_io (to align with prepass_io) - rename `MeshVertexOutput` to `VertexOutput` (to align with prepass_io) - move `Vertex` from mesh.wgsl into here (to align with prepass_io) prepass_io: - remove `FragmentInput`, use `VertexOutput` directly (to align with forward_io) - rename `VertexOutput::clip_position` to `position` (to align with forward_io) pbr.wgsl: - restructure so we don't need `#ifdefs` on the actual entrypoint, use VertexOutput and FragmentOutput in all cases and use #ifdefs to import the right struct definitions. - rearrange to make the flow clearer - move alpha_discard up from `pbr_functions::pbr` to avoid needing to call it on some branches and not others - add a bunch of comments deferred_lighting: - move ssao into the `!unlit` block to reflect forward behaviour correctly - fix compile error with deferred + premultiply_alpha ## Migration Guide in custom material shaders: - `pbr_functions::pbr` no longer calls to `pbr_functions::alpha_discard`. if you were using the `pbr` function in a custom shader with alpha mask mode you now also need to call alpha_discard manually - rename imports of `bevy_pbr::mesh_vertex_output` to `bevy_pbr::forward_io` - rename instances of `MeshVertexOutput` to `VertexOutput` in custom material prepass shaders: - rename instances of `VertexOutput::clip_position` to `VertexOutput::position` 2023-10-13 19:12:40 +00:00			`fn fragment(in: VertexOutput) -> @location(0) vec4<f32> {`
