Here is the code for the scene posted in the images section. You will
probably have to fix the code a little since it always becomes clipped
off at strange places when I post it. Anways, enjoy!

That is interestingly simplistic code for such a wonder effect.

Thanks, I take that as a compliment! I was pleased to find out just how fast
it renders, too.

Every now and again I lurk into these groups and see something that I JUST HAVE TO try
out.  So I
thought that your sun.pov was an enticing reason to download the povray 3.1g source
and build povray
again.  All is going well ... but ...

fade_color is a feature of Nathan Kopp's UVPov 6.x. The source is available
for you to compile if you want to try it on your platform.

Nathans site:
http://nathan.kopp.com/patched.htm

A linux version of the patch is at:
http://www.warmann.com/users/broken/utils/utils.html
(not sure if this feature is in this version)
