Bump with shadows? 2004-02-19 - By Hajo ten Thije

Hi Nacho,
you can only achieve this by displacement map. Bump map only deviates
the surface normals but does not alter the geometry. Take a close look
at the boundary of a simple sphere which has a heavy bump map applied:
it will be perfectly round, although the surface "looks" deformed.
Bump just fakes deformation.
