Or in RL images, for that matter.


BTW:  I found the Voyager 2 pic I mentioned in an earlier post:

<cough> Look closely at the limb on the left hand side.  Also look for the 
whispy dust clouds in the lower right.  The entire planet is contained in a 
media.

Anyhow, here's revision 2 -- at 1024x768x24bpp.

Been there, done that.  Waited a few hours for the render.

could you post the source for this? i tried for a long time to get a
realistic scene like this, but i could not get the textures and lighting
right. i even checked my physics books for sizes and distances of the earth,
moon and sun just for completeness.

the texture on the moon never gave way to the cresent shape we all know and
love.

thanks,
ross

The ship has a triforce on it!?!?

I don't like the ship so far, personally... it's too hard to make out, and
not very detailed... it looks like it's made of large triangles. I'd like to
see a whole *fleet* of ships or something. I dunno.

Arrakis had (has?, will have?) two moons as well.

That's not a Cobra Mk. III, is it? ;)

  That depends in whether you want it to look like a photo or just like
an artistic image.
  Photos of planets and other similar well-illuminated objects in space
do not usually show stars (including the ones taken in the Moon). This is
because the exposure time of the camera is set so that the planet will look
good (ie. not overexposed). Stars are usually too faint to be photographed
with such a short exposure time; photographing the stars would need a longer
exposure time, which would make the planet overexposed (almost white).

  If you ever see a photo of a well-illuminated planet also showing stars,
you can be sure that the photo is fake or at least altered (ie. the stars
have been added later).
