I recognized that, NTL it seems to be possible with isosurfaces.

That wasn't my point, i just meant that it would be better to enter the
function in a common way like an isosurface function than to hardcode it
and introduce a new keyword for each new function.  If it's not possible
to use warps, you maybe should consider using the isosurface function
parser as i first suggested.

Well, it's a bit too much for a tuesday afternoon :-) but anyway it seems
to be a function for whole space although it's constant in one or two
directions.
