To set up a basic Three.js WebXR scene, create a camera rig and integrate the VR button to enable immersive sessions. This establishes the foundational rendering loop required for virtual reality experiences.

VR controllers in Three.js often fail due to incorrect controller handling or mismatched reference spaces. Properly mapping controller inputs and ensuring the correct WebXR reference space resolves these tracking issues.

Optimize Three.js VR performance by minimizing draw calls and utilizing techniques like foveated rendering. Reducing scene complexity ensures the application maintains a high frame rate for immersive experiences.

Implement AR hit testing in Three.js by using WebXR hit test features to find intersections with real-world surfaces. This allows virtual objects to accurately anchor to physical environments.

Three.js supports hand tracking for WebXR applications by utilizing specific WebXR hand tracking modules. This provides detailed joint data for gesture-based interactions in immersive scenes.

The correct reference space for Three.js WebXR depends on the experience type, using local floor for stationary VR and bounded floor for room-scale. Choosing the right space prevents tracking offsets.
