Well, I found that going with a quadratic_spline instead of cubic_spline appears to
almost fix it completely
when sturm is used.
Just now getting back here to post a reply and now I have to leave again.
The pov script was put at povray.scenes.text-files yesterday as if anyone sees this
message try replacing the
cubic_spline type with the quadratic_spline and uncomment the sturm keywords. The
shape has to be adjusted for
but it seems to be the answer. Almost but not quite maybe. I think it might still be
susceptible to problems.
I haven't tried a sor yet.
Bob
