Multiplayer XR — AR / VR

Spatial computing is exponentially more engaging when shared. Multiplayer XR involves synchronizing headset poses, hand movements, and world states.

Module 1: Avatar Interpolation

Network latency is inevitable. To prevent avatars from stuttering, you must interpolate their transforms between network updates.

function updateRemoteAvatar(avatar, targetPosition, targetRotation, delta) {
  avatar.position.lerp(targetPosition, delta * 10);
  avatar.quaternion.slerp(targetRotation, delta * 10);
}

Module 2: WebRTC Data Channels

For 90Hz headset updates, WebSockets (TCP) introduce too much latency. WebRTC Data Channels provide unreliable, unordered UDP transport, which is ideal for streaming fast-paced positional data.
