Dawn is an open-source and cross-platform implementation of theWebGPU standard.More precisely it implementswebgpu.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.
  • Thewebgpu.h version that Dawn implements.
  • A C++ wrapper for thewebgpu.h.
• A "native" implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. Seeper 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.
