Detailed Description

This class extends FollowingTrackball to include the OpenVR HMD transform.

This class extends FollowingTrackball to include the OpenVR HMD transform, resulting in the World->Head transform. That can be combined with the Head->Eye transform to create the per-eye view matrices.
