Dawn, a WebGPU Implementation in C ++, Hacker News

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:
  • (D3D) on Windows
  • Metal on macOS and iOS Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia OpenG L as best effort where available
  • A client-server implementation of WebGPU
  • for applications that are in a sandbox without access to native drivers
