Moving away from traditional stereoscopic 3D for VR headsets (such as the Oculus VR devices) is all the rage now. Microsoft’s HoloLens and Magic Leap‘s upcoming headset are part of this new wave but details of the underlying technology are virtually non-existent. However, a group from Stanford are presenting a paper on their light field stereoscope at SIGGRAPH2015 in Los Angeles next month that describes how the light field technology works. Worth reading if you want to know more about this emerging tech.
Incidentally, I first went to SIGGRAPH in Dallas in 1981. Quite a bit has changed since then!
