Abstract

A view-dependent progressive mesh coding algorithm is proposed in this work to facilitate interactive 3D graphic streaming and browsing. First, a 3D graphic model is split into several partitions. Second, each partition is simplified independently to generate a base model that can be efficiently encoded. Third, topological and geometrical data are reorganized to enable the view dependent transmission. Before the transmission, the server is informed of the viewing parameters. Then, the server can accordingly transmit visible parts in detail, while cutting off invisible parts. Experimental results demonstrate that the proposed algorithm reduces the required transmission bandwidth, and provides an acceptable visual quality even at low bit rates.
