TABLE_TET_MESH is a FORTRAN90 program which computes the Delaunay tetrahedral mesh ("tet mesh") of a set of points in 3D.
Specifically, TABLE_TET_MESH reads a data file containing the coordinates of a set of points in 3D, computes the Delaunay tet mesh, and writes out a file of sets of four node indices that form a mesh of tetrahedrons.
The input node coordinate data file and the output tetrahedron node index file are in the simple TABLE file format, one set of node coordinates or one set of four node indices, respectively, on each line.
A tet mesh of 3d points is the analog of the triangularization of points in 2d. In other words, it is a maximal organization of the points into nonintersecting tetrahedrons. Since it is a Delaunay tet mesh, it has the additional property that, of all maximal tet meshes, this one has the largest minimum angle.
