摘要
Abstract
To detect collision of objects in virtual reality, three intersect vector detection methods are provided in vega developing environment. In the detection methods, LOS interact detection arithmetic is more efficient while less precision,BUMP interact detection arithmetic is more precision while consume much more system resource at run-time, which leads to reduce efficiency of detection. In the paper, a grade detection arithmetic is proposed to improve collision detection efficiency.The improved method uses LOS to initialize analysis collision range and then uses BUMP to precisely detection. Experiment result shows the new method improves detection efficiency and provides detection precision, and has a satisfying collision detection effect in visual simulation system.关键词
