文中讨论了在基于实景图象的虚拟信息空间进行漫游需要解决的图象处理问题及相关算法，进而设计实现了一种满足实时要求的高效多线程漫游机制。

Virtual Information Space is a application environment, integrating multimedia information. The first ability of virtual information space is to give users the capability of wandering around the virtual space smoothly, and keep the consistent of user's visual sense while wandering. This article discusses the image processing problems and algorithms of walking through in panoramic based virtual space, then designs and implements a high performance multithread wandering algorithm.
