  This should get you started:


camera
{ spherical
  location <0, 0, 0>
  look_at <0, 0, 1>
  angle 360
}

light_source { <1000, 5000, -500>, 1 }

sky_sphere
{ pigment
  { gradient y color_map
    { [0 rgb 1]
      [.5 rgb z]
    }
  }
}

// Some cylinders to mark the four compass directions:
cylinder { -y*5, y*5, .1 pigment { rgb x } translate z } // north
cylinder { -y*5, y*5, .1 pigment { rgb y } translate -z } // south
cylinder { -y*5, y*5, .1 pigment { rgb z } translate -x } // west
cylinder { -y*5, y*5, .1 pigment { rgb x+y } translate x } // east

// An example heightfield:
#include "functions.inc"

height_field
{ function 200, 200 { f_noise3d(x*10, y*10, z*10) }
  pigment { rgb <1, .6, .2> }
  translate <-.5, -.8, -.5>
  scale <100, 10, 100>
}
