How to export a THREE.JS scene into a 360 texture for photosphere

问题

Now that youtube supports 360 degree video[1], how can I export a 360 degree frame from THREE.JS scene to be viewable as a photosphere texture or even within a youtube video?

The viewer to use the export could be like the one at http://blog.thematicmapping.org/2014/01/photo-spheres-with-threejs.html

I put together a few different libraries to enable 360 video and photo capture from Three.js

here is what I did.

I set up 6 cameras, captured each viewport and fed it into a 360 shader as texturecube.

It seems you could render two frames from a 180FOV camera, the first aimed at (0,0,1), and the second at (0,0,-1). Next, stitch them into a single image.
