Abstract
An Internet-based interactive walkthrough virtual environment is presented in this work to facilitate interactive streaming and browsing of 3D graphic models across the Internet. The models are compressed by the view-dependent progressive mesh compression algorithm to enable the decorrelation of partitions and finer granularity. Following the fundamental framework of mesh representation, an interactive protocol based on the real time streaming protocol (RTSP) is developed to enhance the interaction between the server and the client. Finally, the data of the virtual world is re-organized and transmitted according to the viewer's requests. Experimental results demonstrate that the proposed algorithm reduces the required transmission bandwidth, and provides an acceptable visual quality even at low bit rates.
