  1. Tele-Immersion Summer 2002

  2. What is Tele-Immersion • Networked Virtual Reality • High Speed Network: Internet 2 • Virtual Reality • computer generated, interactive, three-dimensional environment in which a person is immersed

  3. About Tele-Immersion • Will transform the way people collaborate at a distance • computers recognize the presence and movements of individuals and objects • track those individuals and images • permit them to be projected in realistic, multiple, geographically distributed immersive environments on stereo-immersive surfaces.

  4. Virtual Reality • High performance computer graphics system • Interactive • Immersive • Fully & Partially Immersive

  5. Surround Environments • CAVE (Fully immersive) • 3 rear-projected screens for walls and a reflective projection for the floor • Stereographic LCD shutter glasses • High-resolution, high bandwidth • Computer controlled audio, support multiple speakers • Tracking system for users’ head movements

  6. Surround Environments (cont’d) • Responsive Workbench • Tabletop environment • Stereo graphics via projector-and-mirror system • Shuttered glasses • Tracking system for head, as well as gloves and stylus to interact

  7. Surround Environments (cont’d) • Both CAVE and Responsive Workbench are quite expensive • $1,000,000 for CAVE • Our goal – build low cost VE • $10,000 or less • Horizontal Virtual Table (had before) • Vertical Virtual Table (soon)

  8. Virtual Table @ CAM

  9. Software • VR toolkits: • CavernSoft • VRJuggler • VisAD • Graphic APIs: • Java3D • OpenGL

  10. Hardware • Graphics Chip • Nvidia GeForce4 • Graphics Card • 3DLabs WildcatII 6210 • SGI • Nvidia GeForce4
