Metal needs RenderTarget usage to be added to the texture allocation so the clear can be done using a render pass. Already working for GL which does not have usage flags on creation. Also working on Vulkan which does not need a render pass. We use vkCmdClearColorImage. D3D12 also needs a render pass to clear multisampled textures, but it already requires multisampled textures to be created with RenderTarget flags. To test the behavior, NonzeroTextureCreation tests are expanded, and the ExpectSampledDepthData helper is factored into a more general ExpectSampledFloatData helper.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress 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.h
version that Dawn implements. - A C++ wrapper for the
webgpu.h
.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
