I agree with Snail, it's the best looking rendition thus far put forth in my opinion.  
Me want see moar be done this with.  

Also, Aard, I want to reiterate my desire to see you try this out with a Mars texture.

Like Terragen?

Terragen 2 is completely procedural IIRC...

Actually, you could probably knock up a renderman shader without too much hassle, micropolygon rendering+displacement FTW

Will experiment.

Here's a screenshot from a realtime thing I made using GLSL... crummier atmosphere, and a funky outline. And no AA. Hm bleh.



And also the cubemap for that ugly thing.

[redsniper]

can it make... you know, continents? seas? or just really bland planets in different shades of brown?

[Aardwolf]

It can't make continents, seas, or bland planets in different shades of brown. It's not making the texture, it's rendering the planet. I made the texture myself... although I did add a few utility functions to make it easier to modify cubemap textures without introducing significant distortion.

OH! I thought it was a procedural texture generator AND renderer. My bad.
