It depends on the type of expression.

Functions that look like f(x,y)=z are easy as you can evaluate the elevations of flat grids.

Functions that look like f1(u,v)=x; f2(u,v)=y; f3(u,v)=z are a bit more work but can be done (they typically give problems with seams when you're fitting nurbs data to the samples.

3D Implicit functions are not possible without using plug-ins, 2D implicit can be done because it can be reduced to a Mesh|Plane intersection.

I'll upload some files that show the above three cases.

Amazing, thx.
