基于Jack的VR环境下碰撞检测问题的研究

Research on Collision Detection in Jack-based VE

在虚拟现实系统中,碰撞检测是影响系统实时性的重要因素。该文对基于Jack的VR环境下的碰撞检测算法的特点和适用范围作了分析和介绍,并从场景中对象间的碰撞检测的管理角度,提出了使用碰撞队列来对对象间的碰撞进行组织和管理的方法,并提出了通过对碰撞队列中对象进行控制,以及对碰撞队列进行过滤等途径,来提高碰撞检测效率的方法。

In VR,collision detection is a key factor which influences the realtime performance.In this paper,the features and the application condition of collision detection algorithms in Jack are analyzed and introduced,also,the collision queue used to organize and manage colliding objects are presented,and the approaches that improve the efficency of collision detection by manipulating elements in collision queue and filtering the collision queue,are given.
