Well, I left it running overnight, and it hasn't finished the second radiosity
pass yet, so it's time to do some major optimizing - splitting the isosurfaces
into sections, tightening the bounding boxes, etc.  Unfortunately, I can't do
much with the functions - in fact, one of the functions is already a
simplification, and needs to be a bit more complex to get the surface I want.

If I come up with something specific I need help with I'll post in the general
group for some ideas :)

On another note, remember what an annoyingly faithful proselytizer I used to be?
 I'm now atheist.  It took me a long time to admit it, but what people were
saying they believed didn't line up with what I actually saw happening in life.
