void testSpringRelaxSinglePoint3 ()
 Tests the spring relax of a point. Uses the TIN below. We are relaxing point 4 and it has 3 connections to the upper edge, 2 connection to the middle and 1 connection to the bottom edge. The result is that the points is "pulled" toward the upper edge. This is not desirable for pre quad mesh generation. More...
