| Abstract: | Realimage based Virtual Information Space is a application environment integrating Multimedia information. The first ability of virtual Information Space is to give the user a capability of smoothly wandering around the Information Space in realtime, and keep the consistent of user's visual sense while wandering. This article discusses the problem of memory caching and threads synchronization for realtime walkthrough, and designs a high performance multithread walkthrough mechanism. |
