虚拟仿真中碰撞检测系统设计与实现

碰撞检测是虚拟仿真中的重要环节.针对碰撞检测中存在多个不同尺寸、不同运动状态的不规则物体场景,研发了一种碰撞检测系统.结合空间剖分技术与方向包围盒层次树实现碰撞检测,对物体间相交穿透问题进行回退处理.系统中设计了场景构建、预处理、实时检测功能,对各功能执行效果加以可视化.结果表明,系统具有良好的检测效率和真实感.

Design and Implementation of Collision Detection System in Virtual Simulation

Collision detection is an important part of virtual simulation.A collision detection system is developed for the scene of many irregular objects with different sizes and different motion states.The system combines space subdivision technology and oriented bounding box hierarchy tree for collision detection, conducting the regression for penetration problem in colliding objects.The system can not only design scene building function,preprocessing function and real-time detecting function,but realize the visualization of each function.The application result shows that the system has good detection efficiency and realism,and provides reliable collision results to support collision response.
