This image looks very weird.

Can you explain a little bit more about
what you are doing ?

Are you "moving" around a mesh on the
surface of a cylinder and recalculating
3 coordinates relative to the 2D-surface
of the cylinder ? And thereafter regene-
rating the whole surface with these new
coordinates. ?

(Two coordinates being cylindrical co-
ordinates and a third coordinate being
the distance from the mesh surface
to the surface of the cylinder. ?)
