Webgpu (I): basic concepts

WebGPU

WebGP Technology can be in Web Achieve high performance on 3D Parallel calculation of graphics and data .

What is? WebGPU

WebGPU It's a new one WebAPI, It presents modern computer graphics capabilities , especially Direct3D 12( Microsoft ), Metal（ Apple ）, as well as Vulkan( Konas organization ), In the graphic processing unit （GPU） The above implementation of rendering and computing operations .

WebGPU The purpose of is similar to WebGL Series of API, however WebGPU have access to GPU More advanced features .WebGL It is mainly used for drawing images , But with some efforts, it can also be used for other operations ,WebGPU For in GPU Provides the best support for general operations on .
after W3C’s “GPU for the Web” Community Group Four years of development ,WebGPU Developers can already Chrome The browser tries to use and API as well as shading language（ An image programming language ） Provide feedback .

about Computer Shader It can be understood as an operation , Independent of traditional rendering pipelines .

Platform support

1. JavaScript API

at present Google Developer A set of JavaScript Of API course .

2. Dawn
   This is a set that can be used C/C++ Realization WebGPU Functional Open source library .
   Because of time , The next step should be to directly learn this set of open source libraries for development .
   utilize Emscripten Compiled into WebAssembly Use in browser .

3. Wgpu
   Wgpu yes Firefox Used in WebGPU One of the Rust Realization . It has been Rust Various in the ecosystem GPU Application used , for example Veloren, A multi person voxel RPG.
