This image shows the comparison of our method with two methods used in
the past. We use fewer triangles to represent the models without any loss
in visual quality of the image
The first picture is a tessellation produced by
Rockwood et.al's method. The second picture is produces using
et.al.'s method and the third picture is produced using our method.
The number of triangles in the three pictures are about 700, 600 and 500
