Locomotion: Going places in VR
summary
Builds a WebXR scene with three.js that adds an enter VR button, enables renderer.xr.enabled and uses renderer.setAnimationLoop so the headset display syncs correctly. Implements controller models from the immersive web assets, tests in a Firefox Reality emulator and on an Oculus Quest, and implements teleportation by rendering a curved guide computed as a projectile arc using quadratic formula to find floor impact. Notes GPU switching, performance tradeoffs, and comfort fixes (linear motion, peripheral frame, optional fade).
