As the underlying rendering engine of AntV, G is dedicated to provide consistent and high performance 2D / 3D graphics rendering capabilities for upper layer products, adapting all underlying rendering APIs (Canvas2D / SVG / WebGL / WebGPU / CanvasKit / Node.js) on the web side. In particular, it provides GPGPU support for algorithms suitable for parallel computing in graph scenarios.
Easy-to-use API。The graphics and event system is compatible with DOM Element & Event API, and the animation system is compatible with Web Animations API, which can be adapted to the existing ecosystem of Web side such as D3, Hammer.js gesture library, etc. at a very low cost.
Support multiple rendering environments。Support Canvas2D / SVG / WebGL / WebGPU / CanvasKit and runtime switching, and also server-side rendering.
High performance rendering and computing。WebGPU-based GPGPU support for parallelizable algorithms. webgpu-graph is a library of graph analysis algorithms using GPU acceleration.
