Movement in VR Mode

Hi,

This might not be the correct thread for this question, but I’m not quite sure where to ask it.

I would quite like to know how the Movement in VR Mode was implemented since I have a very similar movement in mind for what I am currently working on (specifically dragging, scaling and teleporting along an arc and rescaling it to 1:1 size).
I really like how smooth the movement is and I would truly appreciate it if you could add a description of how this works exactly.

Thanks a lot!
