A browser implementation of Augmented Vertex Block Descent, the SIGGRAPH 2025 rigid body solver by Giles, Diaz and Yuksel.
There are two interchangeable backends behind one scene graph: an f64 CPU engine and a WebGPU compute backend that solves the same equations in parallel and handles scenes of tens of thousands of bodies. No build step, no dependencies.
