What It Does

webphysics is an experimental WebGPU-accelerated rigid-body and soft-body physics engine implementing the AVBD (Augmented Vertex Block Descent) solver from Giles et al. (2025). It runs entirely on the GPU using WebGPU compute shaders and supports:

Rigid-body simulation with contacts, friction, and joints

GPU broad-phase collision detection via LBVH (Linear BVH)

Narrow-phase manifold generation with warm-start persistence

Graph-coloring-based parallel body solves

Springs and soft-body constraints

Body sleeping/diagnostics

Browser support: Chrome only (requires WebGPU). This is an experimental proof-of-concept, not a production library.
