Oculus Medium and Rift
I have been working in Virtual Reality modeling for a few years now, very recently switching to Augmented Reality in CAD. Medium is a great program to model with either geometry or with virtual clay. I have a lot of work to do to become more proficient. It is however coming along. What is great about Medium as a platform is I can save the computer models directly to STL files for 3D printing operations at scale with little after model down time.
