Detailed Description

Generator which creates triangular mesh by Triangle library authored by Jonathan Richard Shewchuk.

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.
