This is intriguing stuff - I'd love to be able to generate photogrammetry scans myself using this technique.

One odd thing: although you are looking at a 3D model, it does not appear to be rendered in-headset in 3D. That is, the left eye and right eyes views are identical, which is a real shame as it limits the impact. Is there a reason for this? I assume it would be straightforward to enable stereoscopic rendering?
