React, Meet Virtual Reality
summary
Claim: React can drive VR with native performance if the rendering model changes. Builds a mobile VR engine using Oculus Mobile SDK, embeds SpiderMonkey after a failed Node/js approach, experiments with BGFX (850 fps demo) then moves to a retained scene graph + models approach that scales from 5 laggy/9-crash cubes to ~80 cubes smoothly, adds Bullet for collisions, Assimp for model import and simple React bindings; works well for visuals but lacks spatial audio, shader polish and browser-level WebVR optimizations.
