I'm not sure if there is a built-in way with a single video file, I'll check and get back to you. If not, it maybe necessary to create two separate videos from the one video. Then apply each video to its own sphere that's rendered to only one eye. In this case, modify the code
here to use two spheres and then add the code below:
Code:
sphereLeft.disable(viz.RENDER_RIGHT)
sphereRight.disable(viz.RENDER_LEFT)
