But you can't have an iterative user-defined function to define an isosurface,
right?  I believe that's the kind of thing Darren is talking about - being able
to create your own iterative functions and using those to create objects,
without having to resort to approximating them with meshes.

It's irrelevant to this situation to say that you can use builtin fractal
patterns with isosurfaces because that only includes the julia and madelbrot
sets.  These two fractals aren't appropriate for generating landscapes; you need
to be able to have user-defined iterative functions, and that's not currently
possible.
