摘要:
碰撞检测是虚拟现实系统的一个重要组成部分,它对虚拟场景漫游及动态元素表达的真实性起着至关重要的作用。但同时它也会占用的较多的系统资源,降低实时渲染效率。分析比较了几种常用的碰撞检测算法,并根据虚拟海洋环境自身的特点,采用基于高度图的地形碰撞检测法、包围球法、沿坐标轴的包围盒法相结合的方法对虚拟海洋平台的碰撞检测功能进行了实现。同时对碰撞发生后的碰撞反应进行了研究。在保证实时渲染的要求下有效地提高了虚拟海洋环境的真实感和用户的沉浸感
Abstract:
Collision detection is an important component of virtual reality system.It plays a vital role in the reality of the virtual navigation and expression of dynamic elements.But it will also take up more system resources and reduce the efficiency of real-time rendering.Compared several commonly used collision detection algorithms.And then according to characteristics of virtual marine environment itself,the collision detection function of VR-Ocean platform was achieved by combining a variety of collision detection algorithm.These algorithms included terrain collision detection algorithm based elevation map,Bounding Sphere algorithm and Axis-Aligned Bounding Box algorithm.At the same time,the collision reaction was studied.The results show that this method effectively improved the realism and user immersion of the virtual marine environment in the request to real-time rendering
