Robust transmission of 3D geometry over lossy networks

This paper describes a robust mechanism for transmitting 3D meshes over the Internet. TCP/IP is an excellent means for reliable transport over the Internet. However, multi-user, real-time graphics applications may find TCP transmission disadvantageous when reception of a mesh is time-critical. To improve speed one could use an unreliable transmission protocol. Yet typical mesh compression schemes increase the fragility of the mesh to lossy transmission. In this paper, we develop a hybrid method of transmitting meshes over the Internet, built upon progressive mesh [17] technology. The hybrid method transmits important visual detail in a lossless manner, but trades off loss of visually less important detail for transmission speed. Tests of the method in a lossy network environment show that the method improves the transmission time of the mesh with little degradation in quality.
