WebXR Physics Sandbox

Play a browser-based VR physics game on Quest 3 or desktop: walk the lab, resize the room, change gravity in real time, and launch bouncing balls with charge-based force to study bounce decay.

Quest 3 WebXR: once the page loads over HTTPS or localhost, use Enter VR for headset mode. Left grip slows time, right grip speeds time, A toggles Earth/Moon gravity, B toggles the default or 50m room, X toggles the dotted vector line, and Y toggles default or 70% bounciness.
