Supported in part by NSF Grant CMS-9318163 and an NSERC 1967 Scholarship. There is no warranty whatsoever. Use at your own risk. Triangle generates exact Delaunay triangulations, constrained Delaunay triangulations, conforming Delaunay triangulations, Voronoi diagrams, and high-quality triangular meshes. The latter can be generated with no small or large angles, and are thus suitable for finite element analysis. Show Me graphically displays the contents of the geometric files used by Triangle. Show Me can also write images in PostScript form. Information on the algorithms used by Triangle, including complete references, can be found in the comments at the beginning of the triangle.c source file. Another listing of these references, with PostScript copies of some of the papers, is available from the Web page http://www.cs.cmu.edu/~quake/triangle.research.html ------------------------------------------------------------------------------ These programs may be freely redistributed under the condition that the copyright notices (including the copy of this notice in the code comments and the copyright notice printed when the `-h' switch is selected) are not removed, and no compensation is received.
