摘　　要：在视景仿真中,经常会出现运动实体穿入或穿透其他实体的现象,而用现有的各类包围盒模型不能很好地处理这一问题。为了解决这个问题,介绍了包围盒方法,分析了实体平动、转动、组合运动及相应包围盒的碰撞检测;针对所发现的问题,提出动态碰撞检测方法,并建立了运动实体的动态碰撞检测模型;运用OpenGVS图形引擎,通过VC++编程对模型进行了仿真,通过对仿真结果的对比实验,验证了模型的可行性。In the visual simulation,it often appears that a moving entity penetrates or penetrates through other entities. But the current kinds of bounding box models can t deal with this problem well. In order to resolve it,the method of bounding box is introduced,and entity translation,rotary motion,aggregate motion and collision detection of its bounding box are analyzed. For the problems that are found out,the method of dynamic collision detection is put forward,and the dynamic collision detection models of movin...
