Sorry, I was in a hurry as I posted the first time and I wanted to give you a
quick hint. I rendered your example without anti aliasing (aa) and with the
aa-standard shipped with the Windows version. The first test yielded annoying
"steps" at the curved surface, the second a much more smooth result.  If you are
a Linux user, you should use an ini-file to specify the aa-settings. Something
like this should help:

Antialias=on

Antialias_Threshold=0.3
Antialias_Depth=9
Input_File_Name=isotest.pov

Width=1920
Height=1080


Best regards,
Michael
