Very nice, especially the brown one. Is it my imagination (I'm usually wrong
on things like this...), or does the lower left one appear kind of pointed
on top?

Regards,
Dave

ha! it does look pointy! of course, it's not.  i'm sure if i rotated it
a bit the dark and light area on the image map would go better with the
real light and shadowed areas of the sphere.  oh well, maybe i should
clip and rescale the image...

Maybe it's because it's the familiar Jupiter look of it.  I like the upper
left one secondly.

Could spots that look like Jupiter's Great Red Spot be made?  These planets
can be done with gradients.  How can spots be made within POV-Ray?  If a map
is made within POV-Ray, image_map it once onto a rectangular polygon with a
2:1 aspect ratio to make a map.  All of the maps I have downloaded are 2:1.

The shadows seems a bit bright.. a thick atmosphere and/or moonlight can
help spread the light around a little, but generally, shadows in space
are very, VERY dark (you'd be amazed just how weak ambient starlight is
by itself).

Yes, in a way, using the 'black_hole' warp in the pigment.  Problem is you
need a color for it already present in the gradient color map, and it's just
not easy to work with in my experience anyway.  A layered texture could do
fairly well but then you don't get the good transition from lines to spot you
could get with the warp.

Not intentionally moving in on you Ryan but I've posted my idea of Jupiter at
povray.text.scene-files, can't miss it, subject says "Jupiter-like".  Nothing
perfected about it at
all, something for anyone to tinker with though.

i was thinking it would be cool if there were a "spin" and a "wind"
pattern or warp in povray.  what you would do is use it in a layered
texture.  all other layers would define the patterns and colors, and
then the wind and spin would streak it in a certain direction.  wind
would be linear and spin would be axial.  any programmers out there
reading this?

say hello to mister gamma.  on my monitor, the shadows ARE very dark. 
no color at all.:(  maybe i should do that gamma test someone mentioned.
