Past Work:

BLUIsculpt:

While a student at UAF, I was a member of the BLUI project which is investigating computer user interface design in virtual reality environments.  BLUIsculpt is a virtual sculpting program and the most well known product of the BLUI project.  The source code for BLUIsculpt is available on sourceforge.  BLUIsculpt is the brainchild of Bill Brody, Dr Chris Hartman, and Dr Glenn Chappell.

Qubicle:

Qubicle was the main focus of the research I did while a student assistant at ARSC.  Dr. Glenn G. Chappell (UAF CS department) was the inspiration behind this project and my mentor.  Qubicle is an exploration into common object interfaces in Virtual Reality.
