Research and Implementation of Collision Detection in Virtual Marine Environment
摘要
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.关键词
