The same applies for  MegaPOV, in a way. And it has the advantage that a
mathematical pattern can be used to displacement-map a mathematical object
(isosurface).
I still say displacement-mapping a mesh is a modeller feature, since it simply
transforms the mesh vertices (at least I presume Max does it that way).
