大规模刚体物理

110k rigid bodies in real time, in a browser tab. Grab anything, fire cannonballs.

Built with Claude Opus 5.5: Augmented Vertex Block Descent (SIGGRAPH 2025, Giles, Diaz & Yuksel) in WebGPU with @threejs . It's a physics solver that stays stable with huge scenes and big mass ratios. Opus 5.5 even put together this whole demo reel video just from a single text prompt in Claude Code haha 🤯

Try it: https://three-avbd.vercel.app
(recorded on an M4 Max, lighter scenes run fine on older computers or on mobile)

Code's here, MIT licensed. Go build something with it, have fun breaking things: https://github.com/sbobyn/three-avbd
