中文摘要：

提出一种利用混合包围盒优化的碰撞检测方法。该方法根据碰撞相交刚体不同组件的复杂度进行层次设置，在层次包围盒树顶层使用包围球，在其他层使用OBB包围盒以实现碰撞检测功能。与传统方法相比，缩短了碰撞检测时间，提高了碰撞检测速度，实验结果验证了方法的有效性。

英文摘要：

The optimization of hybrid bounding box collision detection method is proposed.The method sets the level according to the complexity of the different components of rigid body collision intersection.At the top of level bounding box the bounding sphere is used,and in the other levels the OBB bounding box is used to realize collision detection.Compared with the traditional methods, this method reduces the collision detection time and increases the speed of collision detection.Experimental results validate the effectiveness of the proposed method.
