I agree with the isosurfaces idea from Slime. I just posted a reply to
another post...

http://news.povray.org/povray.general/thread/%3Cweb.4428b531cc6d48184a366980%40news.povray.org%3E/

with some isosurface examples (subtracting one function from another, etc.)
using an image_map converted into a function. Perhaps some of that would be
useful.

For smoothing the intersections (or transits) between different isosurface
functions, take a look at the POV documentation, section 2.3.3.3.6
Combining Isosurface Functions.
