triangulation_orient_test


triangulation_orient_test, a MATLAB program which calls triangulation_orient() to read a triangulation, and reorient each triangle that has a negative area. If at least one such triangle is encountered, the program writes out a new copy of the triangle file in which all the triangles have been correctly oriented.
