- Add a Configuration struct to the WebGPUPlatform class. This allows for client-side setting of WebGPU backend configurations. - Add a configuration for forcing the wgpu backend to pick a certain backend. - Add Vulkan as a potential backend for WebGPU + MacOS. - Locally modify Dawn so that it does not assume only switfshader is available for Vulkan on MacOS. - Enable vulkan support for Dawn (third_party/dawn/tnt/CMakeLists.txt) - Plumb option to pick different WebGPU backend through FilamentApp and gltf_viewer.
Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
- Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
