摘　　要：针对虚拟场景中碰撞检测的实时性与准确性这对矛盾,根据地形平均曲率将地形划分为三种类型,不同类型的地形采用不同地形匹配算法;提出了三维实体模型内部碰撞检测这一环节,避免了实际运用过程中坦克火炮身管穿透尾部副油箱这一与实际不符的现象;采用混合包围盒算法,较好地解决了坦克与其它实体模型的碰撞检测问题。在某模拟训练系统中应用效果较好。In order to solve the contradiction between real-time and accuracy of collision detection in virtual scene, we divide the terrain into three types according to its average curvature, and different matching algorithm is used for different types of terrain. In the actual process of applying, collision detection of three-dimensional solid model itself is put forward to avoid the inconsistent with the actual phenomena that Tank Gun Barrel penetrating the rear fuel tank. Mixed bounding box algorithm is used to solve the problem of collision detection between tanks and other entities models well. The application is better in a simulation training system.
