To set up an immersive-vr session for Meta Quest using Three.js, you need to initialize the XR session with local-floor support and configure the camera rig architecture. This ensures proper tracking, hand interactions, and rendering within the VR environment.

In WebXR, immersive-vr replaces the real world with a virtual environment, while immersive-ar overlays virtual 3D objects onto the user's physical surroundings. Choosing the right mode depends on whether your Meta Quest app needs full virtual immersion or spatial augmented reality.

Achieving native framebuffer resolution in WebXR requires configuring the WebGL renderer to match the Meta Quest headset's exact display parameters. Proper handling of shaders and avoiding post-processing incompatibilities are also critical to maintain optimal visual fidelity and performance.

Geometry inversion in WebXR typically occurs due to incorrect coordinate space handling or mismatched camera rig transformations. Fixing it involves aligning your Three.js scene's coordinate space with the WebXR tracking references and validating your local floor setup.

The best way to implement locomotion and UI panels in a Meta Quest VR app is by using a dedicated camera rig architecture for movement and attaching UI panels to the controllers or view space. This approach ensures intuitive interactions and comfortable user navigation.

Post-processing often encounters incompatibilities with WebXR on Meta Quest due to stereo rendering pipeline conflicts and native framebuffer resolution constraints. You should carefully validate your shader considerations and test performance impacts when applying post-processing effects.
