摘要
研究了约束Delaunay三角网生成算法 ,并在无约束数据的Delaunay三角网基础上 ,提出了一种快速嵌入约束线段的算法 ,同时借助OpenGL开放式三维环境 ,对三角网进行光照渲染等处理 ,实现了地形三维可视化 。
This paper researches the algorithm of the Constrained Delaunay Triangulation Net generation . Based on the normal Delaunay Triangulation Net, a fast embedding constrained segments algorithm is put forward .At the same time, resorting to the three dimension open environment of the OpenGL, the TIN is disposed of by Lighting and coloring in order to realize three dimension visualization and fulfilling the needs of many applications.
