triangulation_quality


triangulation_quality, a MATLAB code which computes and prints a variety of 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.

Usage:

triangulation_quality ( 'prefix' )
where 'prefix' is the common prefix for the node and triangle files
