There is a San Diego VR meetup group. There was a presentation on photogrammatry which is a process which let’s you take a set of still photos from multiple vantage points and use software to reconstruct a 3D representation of the scene. It tries to reconstruct the scene by matching common reference points between the images. I also got a chance to try out the Hololens while there too which was cool. On the plus side, it was really nice that it was completely wireless and the displays and rendering was good, stable and solid. However, the field of view was pretty small, and the user interface of tapping in the air was a little awkward. Glad I got a chance to try it.
