TRIANGULATION_QUALITY, a C++ 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 is available in a C++ version and a FORTRAN90 version and a MATLAB version.
TET_MESH_QUALITY, a C++ program which computes quality measures of a tetrahedral mesh.
TRIANGLE is a C program which computes a triangulation of a geometric region.
TRIANGULATION a C++ library which carries out various operations on order 3 ("linear") or order 6 ("quadratic") triangulations.
TRIANGULATION_NODE_TO_ELEMENT, a C++ program which reads files describing a set of nodes, their triangulation, and the value of one or more quantities at each node, and outputs a file that averages the quantities for each element. This operation in effect creates an "order1" finite element model of the data.

TRIANGULATION_ORDER6 is a directory which contains a description and examples of order 6 triangulations.
