Hi,

Thank you ! That's a really interesting piece of script. I may use

agree ? Anyway, do you think that it may also work with MegaPov 0.7 ?
In this case, waiting for Povray 3.5 UNIX/Linux code release, I
may compile MegaPov for my ATARI (I'm on the way), and test your
scripts. Meanwhile I realized that MegaPov 0.7 parametric surfaces
are really slow to render, and very fast to parse. It's the exact

great miss from MegaPov 0.7, and Povray 3.5 (I suspect), that there's
no cylindrical or spherical coordinates. It seems to be possible
to do with your proper script. So thanks again !

Regards,
