Ja...  Hallo...

I'm a decently new user of POV-Ray -- which I just adore -- and I've
been working on doing the blob modeling...  The problem I have with the
blobs is that I can't figure out how to scale them in relation to the
other objects in my scenes (except by trial and error, of course).

I was hoping someone with a good knowledge of the mathematical side of
the blobs could tell me if there is some way to keep the size of the
blob object constant while changing the threshold -- that is, if I could
model the objects at about .01 threshold then there size is nearly that
of normal components, and then I could adjust the threshold higher to
smooth edges....  Or any similar tips.

One idea I had was to make three related variables:

#declare Thr = .65
#declare Size = 1 + Thr
#declare Weight = 1 + pow(Thr,2)

blob
{
	threshold Thr
	sphere { <0,0,0>,1,Weight scale Size*<1,2,1> }
	...
}

I know that those three aren't related properly there, but it seems to
work fairly well over a range of .35 < Thr < .65

Any ideas are appreciated greatly.
