Software

• The team used the Virtual Reality Peripheral Network (VRPN) project’s software to collect raw data from the input devices, and convert that data into velocities. VRPN seamlessly integrates with VRJuggler, letting CAVE users interact with the virtual worlds created for VRJuggler.

• By the end of this course, I hope to be able to use the OpenGL to display

scientific data.
