So my last post was about the fine details on this planet, and this one is 
definitely about the global scale. I've come up with a nice pattern for 
creating continents with mountain ranges, and made 2 patterns based on that 
to represent temperature and rainfall.

The idea is I can use these patterns to drive the more detailed ones, so 
different vegetation will grow in areas with certain combinations of heat & 
rain.

The patterns are all fairly simple, since all I want is an interesting 
looking planet for my IRTC entry not something super realistic, and since it 
is so simple I've decided to share the source for the main planet pattern:

//--

 pigment_pattern {
  pigment_pattern {
   crackle
   colour_map { [0 rgb 1][1 rgb 0] }
  }
  poly_wave 10
  pigment_map {
   [0
    crackle solid
    colour_map { [0 rgb .3][1 rgb .7] }
   ]
   [1 spotted scale 1]
  }
  scale .5
 }

 #local tecturb = .4;
 warp { turbulence  tecturb octaves 10 }
 warp { turbulence -tecturb octaves 10 }

//--

Feel free to use it if you like it!
