 As you can see, the result is "interesting" and totally wrong. The problem is

+that the PolyCollection will draw the triangles in the order they are given
 while we would like to have them from back to front. This means we need to sort
 them according to their depth. The good news is that we already computed this
 information when we applied the MVP transformation. It is stored in the new z
-coordinates. However, these z values are vertices based while we need to store
