Dawn RT

This is a fork of Dawn which gets extended with a Ray-Tracing extension. The extension is implemented into the Vulkan backend (using VK_KHR_ray_tracing) and the D3D12 backend (using DXR).

The specification of the Ray-Tracing extension can be found here.

The relative WebGPU issue can be found here.

An article covering the basic usage of the API can be found here.

A Chromium build with Ray Tracing capabilities can be found here.

- I'm looking for sponsors to continue working on this project -

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
