摘　　要：研究了动画和碰撞处理中的层次细节技术,提出了动画层次细节二叉树、碰撞层次细节控制矩阵等多种有效的应用解决方法。实验结果表明这些方法应用在存在大量动画和撞碰处理的虚拟三维场景中有效地提高了渲染实时性。Level-of-detail （LOD） technology of animation and collision were studied. Some effective methods such as animation LOD binary tree, and collision LOD control matrix were put forward. Experiment results show that the improvement of rendering on time can be achieved by applying these techniques to three-dimensional scene with numerous animation and collision operations.
