| 摘 要： | 首先简单介绍四叉树的结构、C代码实现地形结构构造,实现动态LOD四又树虚拟地形的绘制.在用四叉树方法进行LOD建模过程中,关键在于怎样对原有的数据进行四叉树分层,LOD地形绘制中要消除由于相邻的节点或块之间分辨率不一致而产生的裂缝.

| Abstract: | Gives an introduction of quad tree structure and uses C code to achieve the terrain structure,accomplishes the drawing of dynamic LOD quad tree virtual terrain.In the process of LOD modeling in quadtree method,the key is how to delaminate quadtree for original data,and eliminate crack which is formed due to distinguishability between adjacent nodes or blocks. |
