Keck Caves at UC Davis does extensive development of virtual reality applications for scientific visualization. There is collaboration between UC Davis and Reno's Desert Research Institute.

From the website: "CAVE QUAKE II is an adaptation of the popular PC game Quake2 for the CAVE, the world's best virtual reality platform! The demo is not a true Quake2 client, but it is quite playable and shows how compelling a game becomes with life-sized stereo graphics!"

FreeVR is a software library for the purpose developing virtual reality applications, allowing for a wide range of hardware and software configurations. FreeVR is developed and maintained by the Center for Advanced Visualization, Computation and Modeling at the Desert Research Institute.

OpenSceneGraph is a free and open source solution to computer graphics requirements for scene management and efficient renderin of objects in the 3D world. This library will be used extensively for the STRAFE project.
