Below you'll see a screenshot of some preliminary adventuring I did today in UE4's VR editor. This feature of the engine has been around for a year or so in trial form, but fairly recently received some more functionality. It was also showcased fairly heavily near the end of Epic Games' "State of Unreal" presentation at the recent Game Developers Conference (GDC) in San Francisco (https://www.youtube.com/watch?v=K6tRt7c2elU).
In small spaces of spare time, I've been forging ahead through UE4 tutorials, attempting to get to a state where I can create a short demo of a Calculus 3 learning tool in roomscale VR. The VR editor should help speed up certain parts of the process, particularly in making in situ changes to look and feel of the environment (as a "player" would experience it).
Although UE4 may be recognized primarily as a tool for game design, it's got some real power as a vehicle for productivity and educational content creation as well. In addition to working hard on math research this summer, I'm hoping I can pull together this demo. Stay tuned for updates!
