I've always wondered if there wasn't any way of generating a 'procedural
heghtfield' and mapping it onto an object. Almost like a normal but using real
height. But, AFAIK you can't map an isosurface to an object so I wouldn't be
able to use that.

BTW can isosurfaces use info from procedural textures ie: making an isosurface
with a crackle height/depth? If so, I gues I would more easily get into
isosurfaces (UnfortunatelyI just don't have al that time to play around looking
for a formula that looks nice - unless of course someone can give me the x,y,z
formulas for all the procedural textures in Pov ;).

I think trace and eval_pigment might be what I'm looking for, but I couldnt'
really find any samples of how to use  them in this way in the documentation.
