| # Dawn, a WebGPU implementation |
| |
| Dawn is an open-source and cross-platform implementation of the work-in-progress [WebGPU](https://webgpu.dev) standard. |
| More precisely it implements [`webgpu.h`](https://github.com/webgpu-native/webgpu-headers/blob/master/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 |
