Firstly,split the set of discrete points into several subsets with a threshold value and built an index binary tree during that process. Secondly it built Delaunay triangulation on these subsets by Graham scanning technique.
首先对平面上的离散点集按一定的阈值进行分块,建立子块索引二叉树,然后利用Graham扫描技术对各子块构建Delaunay三角网,最后自底向上合并具有相同父节点的子块。
