Nymph (Working title.)
Screenshot of a game being produced by Triple Junction Studio LLC.
I have been working on many parts of this game: game code, graphics engine, simulation engine, and art pipeline.

Selection of work done while at the Xbox Advanced Technology Group:

	Xbox Fur Sample In this sample, I took my work done in Microsoft Research on rendering fur in real-time and made it practical to use on the Xbox.
Xbox Grass Sample This sample demonstrates realistic grass with painted stripes and how to transition from fairway to green.
