I played around with something similar in order to create a camera setup for WebGL/Three.js and the Occulus Rift: http://sxp.me/rift/ http://sxp.me/rift/ This was created before my Rift was delivered so I used cross-eyed 3D rather than the proper 3D the Rift uses. The camera setup is general enough that it can probably be applied to any Three.js scene that allows offscreen rendering.
