摘要
文章对距离跟踪算法进行改进,提出了球心距跟踪算法,并利用该算法对Vega Prim e中的BUMP碰撞检测算法进行加速,以排除虚拟战场环境中明显不可能发生碰撞的实体,从而达到减少参与碰撞检测的实体数量的目的。
In the virtual battlefield based on Vega Prime, the number of objects which participate in collision detection will affect the efficiency of collision detection directly. A range tracking algorithm was improved in this article, and the sphere center distance tracking algorithm was advanced. The algorithm can accelerate the BUMP collision detection algorithm in Vega Prime in order to remove the objects that are not impossible to collide with each other in the virtual battlefield apparently, and so as to reduce the number of objects participating in collision detection.
