虚拟场景漫游中基于视点的碰撞检测研究及实现

The Research and Realization of Eye-position Based Collision Detection in Virtual Environment Walkthrough

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.
