| 摘 要： | 实时三维场景快速绘制是实现漫游和仿真的基础，提出了一种基于分层简化和碰撞检测的快速渲染算法．该算法先采用八叉树的分层简化三维场景模型，然后用包围盒实现视景的实时碰撞检测，最后采用基于场景剔除的图像缓存技术．从实验结果分析，此方法在效率和显示效果上是可行的．

| Abstract: | Fast rendering of 3D large-scale scene in real-time is used in the field of navigation and emulation. A fast rendering algorithm based on layered simplification and collision detection is proposed. First, the octree to simplify the 3D mesh models of the whole scene is employed. Then bounding box and image caching of scene culling to implement the view frustum of the collision detection in real-time is used. Experimental results show the high efficiency of this algorithm for fast rendering of large-scale scene. |
