GPU-Side Physics: A Three.js WebGPU Compute Demo

Thousands of instanced bodies tumble and collide, with the entire physics step running on the GPU through WebGPU compute and Three.js TSL. No CPU round trip, no framerate flinch. A clean little workbench from Kevin Levron, built to inspect, tweak, and learn from.

SnookerSim: Snooker With Physics You Can Measure

A 3D snooker table you can just walk up to and play. Side spin curls the cue ball off the cushion, deep screw draws it back, and a cage-and-jaw view shows exactly why your ball rattled out. Physics in plain TypeScript, no off-the-shelf engine. Shareable positions, MP4 capture, real recorded sound.

NullGraph: A Data-Oriented WebGPU Rendering Framework

Vikas Kumar Singh's NullGraph drops the scene graph and streams flat ArrayBuffers straight to the GPU. Strange attractors, Hopf fibrations, curl-noise fluids, and a test engine that lets you swap memory layouts mid-flight to watch the frame times move.

WebPhysics: A WebGPU Implementation of Augmented Vertex Block Descent

Jure Triglav ports the 2025 AVBD solver onto the GPU: stacks that settle instead of jitter, piles with opinions about mass, and an LBVH broad phase feeding colored primal sweeps in parallel. The reference demo is CPU-serial. This one runs in a browser tab.

Starter Kit Racing: mrdoob's Track Editor and Racing Game in Three.js

mrdoob ported Kenney's Starter Kit Racing from Godot to plain JavaScript and Three.js with crashcat physics. Build a track in the editor, race it, share the URL. No build step, no framework, just clean code and low-poly fun.
