Google VR
As part of the VR team, I worked on a variety of projects ranging from VR headsets, to 6DoF tracked controllers, to VR system UI design. I used Unity to create a rapid prototyping environment for the design team to explore VR interaction ideas and built several prototypes of system UI interfaces.
An in-house game engine was used to write the production UI for the headsets we built. This was a C++-based engine built on top of a physically-based realtime renderer called Filament.
