摘　　要：分析虚拟现实系统漫游引擎的设计与实现,提出基于Vega的视点与场景的碰撞检测算法,讨论用鼠标和键盘控制虚拟场景的带碰撞检测的漫游引擎,并把该漫游引擎应用到虚拟校园漫游系统的开发,取得预期的效果．The design and implementation of virtual reality walkthrough engine are analyzed. Based on Vega the model of collision detection in the area of observer and scene is presented. The walkthrough engine with collision detection that use mouse and keyboard to control the virtual scene is discussed. The system is used to implement the virtual campus walkthrough system, which achieves the expected results.

关 键 词：虚拟现实 漫游引擎 碰撞检测 VEGA
