triangulation_quality, a FORTRAN90 code which computes and prints quality measures for a given triangulation of a set of points in 2D.
The triangulation is defined by a node file containing the coordinates of nodes, and a triangle file containing sets of 3 or 6 node indices.
The quality measures computed include:
Each quality measure is defined as the minimum of its value over all the triangles; the maximum and best possible value is 1, and the minimum and worst possible value is 0.
triangulation_quality prefixwhere prefix is the common prefix for the node and element files

triangulation_quality is available in a C++ version and a FORTRAN90 version and a MATLAB version.
TET_MESH_QUALITY, a FORTRAN90 code which computes quality measures of a tetrahedral mesh.
TRIANGULATION, a FORTRAN90 code which carries out various operations on order 3 ("linear") or order 6 ("quadratic") triangulations.
