Multiple-Description Geometry Compression for Networked Interactive 3D Graphics

In web-based visualization applications, such as internet computer games, tele-medicine and so on, 3D geometric data are typically communicated in a distributed and networked environment. The commonly used TCP/IP network protocols can provide reliable transmission, but they often introduce unpredictable delays. On the other hand, users in these applications can tolerate degradation of rendering quality when network conditions deteriorate, but not excessive delay or stoppage of animation sequences.
