+Triangle generates exact Delaunay triangulations, constrained Delaunay
+triangulations, Voronoi diagrams, and quality conforming Delaunay
+triangulations. The latter can be generated with no small angles, and
+are thus suitable for finite element analysis.

+Show Me graphically displays (using X) the contents of geometric files,
+especially those generated by Triangle, my two-dimensional quality mesh
+generator and Delaunay triangulator.
+Show Me can also write PostScript images to files.
