Real-Time Transmission and Rendering in Low-End Environment--Virtual Dunhuang Walkthrough System

A real-time walkthrough system for Dunhuang is described．On the basis of our system，we have experimented with the implementation of real-time transmission and rendering in low-end environment．Dynamic scheduling of texture data is well performed based on our texture-oriented cache hierarchy management，and at the same time we propose some algorithms such as user-behavior-based dead reckoning，and area of interest with selection mechanism．Final result demonstrates the values of our algorithms．
