I have moved the parameters by examination of the structure. I
have played with them by maximizing guesses for parameters. I can
get a lot of effects but I can not get rid of the sharp inverse
curve where they intersect. (That is where you see a highlight
divided by a line rather than fading through a line.) 

	I cannot say "no way" but I can say I spent more time that I
would like to remember on field theory (got a B! and a miracle at
the same time) and I cannot think of a way fields are going to
yield the sharpness of that intersection. I can see that is good
for visualizing molecules and such, but I don't see how this can
arise from field equations. 

	The help file example shows it so it is not clearly me error. 

	Yes, I am using sturm. No difference with or without. 

	My interest is in modeling human bones for images not medical
reasons. I was thinking of smooth transitions with whiles of
blobs that would smoothly transition; maybe two lines of a
hundred for a long bone, four for a phalanx. These lines are
ruining the idea. But if these were truly potential surfaces they
would not be there. 

	So, back to the subject line above.
