虚拟空间物体碰撞检测的一种算法

AN ALGORITHM FOR COLLISION DETECTIONBETWEEN HARD AND OBJECTS IN VIRTUAL ENVIRONMENTS

在虚拟现实技术中 ,人与虚拟空间物体的碰撞检测是非常重要的研究课题之一 .由于空间物体结构的复杂性和碰撞响应的多样性 ,故找出一种通用检测算法是极为困难的 .本文针对飞机机舱内的可操纵物体 :开关、按钮、油门杆、停车杆等 。

In virtual reality, the collision detection between hand and objects in virtual enviornments is a very important subject. Because the complexity of structure of object and the variety of collision response, it is very difficult to provide a general algorithm for all objects. This paper present a real-time accurate algorithm for collision detection between hand and objects in aircraft cabin, such as switch, button, oil handle and brake handle.
