VR rollercoaster

Source-shaped study of the pinned webxr_vr_rollercoaster example: procedural track geometry carries a banking train through seeded terrain, trees, sky, shadow rails, and two rotating funfairs.

VR entry pointimmersive-vr

The visible VRButton preserves the official local reference-space entry point. Desktop QA exercises the WebGL2 scene and synthetic train path; native headset session, pose, and stereo comfort remain unverified.

The route keeps the official RollerCoasterGeometry, RollerCoasterLiftersGeometry, RollerCoasterShadowGeometry, tangent-driven banking, and moving funfairs while using a deterministic terrain adapter.

Runtime stateRUNNING

Source review, implementation, runtime verification, and whole-example fidelity are tracked independently. Official page pixels, random terrain cadence, and native headset behavior are intentionally not claimed by desktop QA.
