| 摘 要： | 针对地形的四叉树简化技术，提出一个简单的裂缝消除算法．该算法不使用递归同样可以使四叉树满足约束条件，简化结果不存在T型连接．利用该算法实现了地形数据的实时显示，并提出了今后的改进思路． |
| 关 键 词： | 大规模地形显示 四叉树 裂缝消除 T型连接 递归 |

| Abstract: | The technique of large-terrain rendering is still in progress. This paper proposes a simple algorithm of crack elimination used in the quad-tree simplification procedure of terrain. The method does not use recursion, when it converts a quad-tree to a restricted quad-tree. The resultant mesh generated is continuous without T-junction. In taking advantage of this algorithm, real-time rendering of large-terrain is achieved. Finally, further improvement is also proposed. |
| Keywords: | large-terrain rendering quad-tree crack elimination T-junction recursion |
