I made a random-planet generator that can create earth-like planets.  Still
struggling with the clouds (they're very hard to do convincingly :-/) but I
think it doesn't look too bad the way it is now.

Comments welcome!

Wow that looks awesome!

I may be able help with the clouds, I had a go at doing a similar thing a 
while ago and got a good cloud effect but could never get the land right! 
I've attached a picture of my attempt, and the source for it.

That's pretty cool. I'd like to see what the function is for generating the
continents. I tried this once and couldn't come up with anything realistic
or even stylized and unrealistic but visually appealing.

nice work

hmm, seems like a good start, I might just be able to use your code! :)
thanks !

this is the pattern that determines the height of the landscape:

  pigment_pattern {
   pigment_pattern {
    crackle scale .75
    poly_wave .125
    warp {turbulence .125 lambda 3}
   }
   pigment_map {
    [0 rgb 0]
    [1 granite scale 10
    scale .5 warp {turbulence .75 lambda 3} scale .5
    ]
   }
  }

That's a very cool idea, I hope you get the clouds sorted out soon. :)

Nice result, Zeger. Congratulations!

What about a close up? ;-)

thanks :)

maybe if I add one more small turbulence, but now it all looks too fuzzy for
close ups :)

Fantastic! Now see how close you can get to the real continents this way ;oD
