Level-of-detail technology of animation and collision in virtual reality
虚拟现实中动画和碰撞的层次细节技术研究及应用

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.
