triangle软件包

Triangle is specialized for creating two-dimensional finite element meshes, but can also perform simpler related tasks such as forming Delaunay triangulations. Here is a sample Planar Straight Line Graph (PSLG), a Delaunay triangulation of its vertices, a constrained Delaunay triangulation of the PSLG, a conforming Delaunay triangulation of the PSLG, and a quality conforming Delaunay triangulation of the PSLG with no angle smaller than twenty-five degrees. The latter is suitable for finite element analysis.
