I mean displacement in the renderman displacement shader sense which
is what Roberto was asking about, hence in this case 'true 
displacement'. A function (in this case a shader)
applied to an object, sphere, mesh, plane etc which change its
geometry.

As I stated IMHO isosurfaces are not displacement as there is no 
original object expect the one created by the function. It doesn't 
matter what you do within that function what you get is still the 
'original' object not a displaced one.

Picky, oh yes.
