Linden labs had produced a VR version of secondlife at least for the oculus DK2. There was also another viewer, ctrl-alt-viewer. Linden seems focused on an altogether new VR platform, Sansar, though that fails to get traction. i guess it s nice to have it, but then you need take off the glasses to chat.
Any ideas if that terrain would be released? It along with the building represents a lot of work and instructive material. And the code includes many .h files. It would be great to see those also.
