But Runes suggestion would be easily available to many users who do not have
your mathmatical skills. Or do not frequent these newsgroups.

Not to start a war because I think Pov and its creators are wonderful. All
to often programs are written by very clever people who don't always realise
how thick the user is!  I'm an artist I trained for many years as one, my
mathamatical skills and programing skills are very limited. I do not have
much time to learn mathamatics at the level you lot work at and at 55 find
that level of thinking increasingly difficult. At the same time my artistic
skills continue to improve and grow.

All I ask is an awarness from the cleverer members of our fraternity that
there is a diversity of users with different needs, which is why I think as
many facilities as possible should be programed directly into Pov in as
simple and easy way to understand and use as possible.

After all those clever people can always amuse themselves by wrinting
patches for mathamatical dummies like me.
