Actually, it would be more comparable. The isosurface isn't composed of 
flat surfaces.

I see.
i wonder how it would work with the height field macros...their 
smoothing function is designed for continuous functions, I never really 
tested it with interpolated image maps. It wouldn't fix the stepping 
problem, but meshes use single-precision floats to store vertices, which 
might be useful if the short integer used in the height field isn't 
enough.
