在测绘或地图学中，经常会需要用高程点生成DEM，一般首先由这些点按最小原则生成三角网，此代码即是根据任意多个点生成Delaunay三角网功能。-In the mapping or cartography often elevation point will need to generate DEM, generally the first point from these principles by the smallest triangulation generated, the code that is generated in accordance with any number of points, Delaunay triangulation function.
