webphysics-avbd-engine Skill by ara.so — Daily 2026 Skills collection. What It Does 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…
