Hello all. After seeing the faked fire post, I was reminded of a cloud
technique I was working on once that involved using discs. I decided to
play with it some more and this is the result.
Oh yeah, it took 2 minutes and 40 seconds to render with no AA on my P
166mhz.
Questions, comments?

Nice cumulus. The shadows from them is a nice touch too.

Very nice clouds -- and fast. Can you share your technique with us?
A full featured macro would be great :-)
Sounds (and looks) very good.

The clouds look excellent but the sun disc looks contrived and unnatural.

I guess this and the fire thing officially usher in the Disk Era of POVing.
We have moved past the Layered Planes Era... may it rest in peace. :)

If I have time I might make a macro, or at least show the technique.

I've since fixed that by putting a transparent disc with phong and specular
highlights behind the sun.

I don't think this will take place of the layered planes. This will only work
in one direction. Adding additional directions might cause the discs to
intersect, which would look bad.

Wow. This disc thing is becoming more and more flexible the more we experiment
with it. Please post samples of how you did this and how you oriented them.

Damnd good image for a test render, bigger and it'd be

Do you really mean this?
It's already on my friggin' hard drive downstairs.

Because the air refracts the sunlight, creating what we see as sky color.

This is not an effect of refraction but, if I remember right ,the colour
blue is in addition a polarisation effect while the "lightness" depends
on the scattering. The air molecules scatter the light. If you look up
then the effect is the smallest and the sky the more blueish. If you
look at the horizion the light has more atmospheric length to scatter so
that the sky shows more of a light blue there.

Refraction is not the keyword here. Rayleigh scattering is responsible
for the color of the sky.

Actually, if you want to get technical, space isn't black in this scene, it's
blue :P

I'm only repeating what I learned in school. I seem to have been
misinformed. It shouldn't happen again. (I'll just keep my mouth shut).

It's a good thing my dad is well into physics and optics because he
explained to me the differences between the Mie and Rayleigh
scattering models when they were first introduced in POV 3.0. Not that
I was ever able to put them to good use, mind you.
