Cobalt

An opinionated 2D node graph based on WebGpu, minimizing CPU usage and maximizing frame rate.

Goals

• pure WebGpu: no fallbacks to WebGl or canvas
• minimal abstractions: provide very light abstractions over what webgpu provides
• gl-matrix/wgpu-matrix compatible: use primitives compatible with how webgpu and webgl store rendering data (float32 arrays)
• works in both browsers and node+SDL
• GC friendly: does not thrash the garbage collector. uses API design that won't allocate memory all over the place
• back-to-front z-indexing
