Very interesting.  Have you seen my isosurface stone walling code?  It looks
to be doing similar sorts of things, though I think mine is a little bit
more intelligent (in that it does things as a stone mason might do, like
making sure stones are wider than tall, etc)  It's slow, since it's in pov
native code, and then uses iso surfaces, but on the other hand, allows for
lots of nifty stuff like roughing up the surface and morphing it into cones
and cylinders and such by changing the iso function.

I haven't looked at your code since I'm pretty much a novice to the POV
source.
