Here's an example of stereo rendering with the Rift using QML and Qt3D, but I haven't tried it out yet:
Also I'm setting the heightAngle, aspectRatio, nearDistance and farDistance of the camera, according to the values used in the example.
Unfortunately this doesn't create the results I was hoping for. Coins Cube is too wide apart so the two images won't align properly when viewed through the rift.
