虚拟场景漫游中基于视点的碰撞检测研究及实现

摘要

碰撞检测是实现虚拟场景漫游重要组成部分,精确、实时的碰撞检测是提高场景漫游真实性,增强用户沉浸感的重要手段.提出了基于视点的碰撞检测方法,并通过改进该算法实现了漫游过程中的地形跟随.实践证明,所提出的方法能够满足实际应用需求.%Collision detection is an important part of virtual environment walkthrough. The exact and real-time collision detection can enhance the reality of virtual environment, improve the immersion of system user. In this paper, we present the collision detection based on eye-position and improve it to realize terrain follow in walkthrough. Practice shows that the method presented in this paper can meet our requirement. At last, we present the method of optimizing the arithmetic.
