This has been done many times--in fact, not so long ago someone was
using some rather advanced techniques with very nice results, but I
couldn't find the post or remember who was doing it. In any case, I was
inspired last night to make a POV planet, and here it is. I'm fond of
the atmosphere and the water, but I should keep working on the texture
for the landmasses.

Beatiful, as always ;-)

Thanks for the nice comments. Here's another, larger render. This one
I rendered with beta 35, and the media seems to have rendered quite
substantially different. I had to do some post-processing to make up
for it.
In case you were curious, the land forms are an isosurface based on
F_ridged; the ocean is a transparent sphere with colored fade statements
in the interior. I used two separate spheres with media--one for
general atmosphere and another for clouds.

The dark side of the planet in this render features a few lights. Are these
city-lights (intentionally placed) or stars from the background shining
through or artifacts (from beta)?

Ah yes, I forgot to mention that. The render did show some artifacts on
the landmasses on the dark side of the planet. However, their placement
seemed realistic enough to serve as city-lights, so I boosted their
brightness and blurred them slightly in post-processing.

Any chance of posting the code? This is something I have played with a
few times but never got this good a result.

I had to change a lot in my media statements when changing from 3.6 to 3.7
beta, but it looked better in the end :)

You could also just put a smaller black sphere inside to stop anything
from shining through. Did you try playing around with the isosurface
accuracy setting?

An inner sphere is a good idea which would probably fix it. I did have
to boost the accuracy setting 1000 fold already just to prevent the
coastlines from showing up black, for some reason.
