Perhaps I invented the wheel twice - once again, but I didn't find the
lathe
object yesterday evening when I encountered problems with the SOR
object. And
I didn't try the storm root solver....

However you can see what my problem looks like in a message with the
same subject in /povray/binaries/images and you can see there what this
new macro

   THE MESH OF REVOLUTION

does!

Uwe.

Jaime Vives has a macro that is similar to what you describe (I
haven't read your macro itself) on his web page (www.ctav.es/jaime/).
Meshing a sor/lathe object has an advantage you may not yet have
noticed: glass (i.e. transparent objects with an ior) is much, much
faster as mesh than as lathe.

I didn't try that - yet - but I finally got around the problems I had
with the original POV-Ray objects though. I tried SOR and the STURM root
solving obtion and there still where some fuzzy features in the image.
FInally I got it to work using bicubic LATHE and STURM ...
Perhaps there should be a warning sign in the online documentation of
the SOR object:
"Using this object might or will result in unwanted pixels in your scene
and unpredictable results. Use LATHE instead!"
