One thing to quickly try would be to use an image as a
displacement map in an package such as Alias PowerAnimator
to displace a fine grid (NURBS or polymesh) and then output
the result as a .stl file.

I have Alias on my machine but don't have access to an RP
system :-( If someone wants a .stl file to try this out I could
post one to this mailing list.. Let me know.
