摘要
Vega Prime提供的相交矢量碰撞检测算法不适用于对精度要求较高的视景仿真系统。针对该类问题,采用层次包围盒,以及结合一维空间排序法思想,提出一种新型高效碰撞检测算法。通过将该算法在制导弹药视景仿真系统中进行实现后,分别与相交矢量碰撞检测算法、传统OBB包围盒算法进行对比试验和分析。结果表明,该算法不仅解决了相交矢量算法出现的"穿透"等失真问题,还提高了仿真的效率,满足了视景仿真系统的高精度要求。
The intersecting vector correlation detection algorithm provided by the Vega Prime does not suitable for those scene simu｜ation systems with highly precise demands. To solve this problem, we bring forward a new effective collision detection algorithm which uses the hierarchical bounding volumes and is in combination with the one-dimensional space sequencing conception. This algorithm has been implemented in guided projectile navigation scene simulation system, and is then used in contrastive test and analyses with the intersecting vector algorithm and the traditional OBB bounding box algorithm respectively afterwards. The results indicate that the new algorithm resolves the distortion problem such as ＂penetration＂ occurred in intersecting vector algorithm, and also improves simulation efficiency, meets the highly precise demands of scene simulation systems.
