   Well... I'm sure I did barely understand what I was doing at the time,
so now I'm really lost. Looking at it, seems just a hack by moving the
mesh vertexes along the z axis (the pow function is being used to move
them proportionally to their distance from the center of the mesh).

   Not really, but if you're going for the mesh camera approach, you
should create a mesh that resembles the lens you are trying to simulate.
