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.
• 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
