Hi,

I'm looking for a macro/scene file which will generate planet maps and
output them into files.

I need to generate planet (flat) maps and also use them as spherical map.

Does it exist ? If not, how can I do this ?
I've found "Blender World Forge"
(http://www.selleri.org/Blender/scripts/text.html), but I want to do this
with POV-Ray :)

Thanks.

  You mean something like this?


// Render for example at -w800 -h400 +a0.1
camera
{ spherical
  location 0
}

sphere
{ 0, 1 inverse
  pigment
  { bozo color_map
    { [0 rgb <0,0,.7>]
      [.55 rgb <.2,.5,1>]
      [.55 rgb <.4,.8,.4>]
      [.8 rgb <.7,.5,.2>]
      [1 rgb <1,1,1>]
    }
    scale .5
    turbulence 1
  }
  finish { ambient 1 }
}

Yeah ! I exactly meant this ! Your scene file is pretty cool :)

Now I need to set colors proportion (eg. 70% brown earth, 30% blue water) or
have random colors.
Next, texturize a spere with the map and add some cloud effect or any kind
of atmospheric effects.

Are there any scripting facilities in POV-Ray in order to generate n bmp
files ? With 1 < n < 1000.

So it will be:
- 1_flat.bmp
- 2_flat.bmp
- ....
- 999_flat.bmp
- 1000_flat.bmp

And:
- 1_sphere.bmp
- 2_sphere.bmp
- ....
- 999_sphere.bmp
- 1000_sphere.bmp

  Read the documentation about animation.
