I am willing to give any assistance you need.

Hi Chris.
I was just messing with the compile Lutz-Peter made. It would appear
there are some major shadow bugs present. For instance, sometimes the
blob object won't self-shadow. Also, when a non-blob object intersects
the blob, the resulting shadow cast by the blob is often incomplete.
There is another problem which happens sporadically. A little hole will
sometimes appear in the blob object, and it can't be fixed with a higher
accuracy or max_gradient.
I'm sure you are aware of these problems, but I can send you examples if
you need me to.
I don't know how far I'll get on the docs. I don't want to clog up the
text with too many 'sorry but...'s.
Happy POV-ing

P.S. The blob2 patch is really cool. I think people are going to be
happy with what they'll be able to do with it. I've done several tests
which indicate a fast render time compared to isosurfaces of the same
quality. I hope you don't give up development on this one :)

My solver doesn't seem to be any better as far as avoiding artifacts
than the original blob solver...I've come across this type of thing a
couple times, and haven't tracked down why it's happening. More test
cases are always useful, send them my way...

Part of this is that the "container" for the blob2 consists of the
bounding shapes for the blob components. Thus, it fits closer and
follows the surface more, letting the solver find roots more quickly.
