IMAGE DESCRIPTION: 

  Standing on top of a mountain after a strenuous climb, looking out at the
  scenery.  Nature is revealed in all its majesty from such remote places!


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

  The landscape was created as a height-field in hf-lab and tiled in a
  12x12 grid and then textured using slope-dependent textures.

  The trees were created as a mesh using POV's wonderful while loops in
  conjunction with TMPov's hf_height_at (to give the height of the
  height-field at a given point).  The position of each tree was contrained
  to fall only between a given minimum altitude and a given maximum
  altitude, and only on a spot that was no steeper than a given maximum
  agnel.  The generated mesh was then tiled with the height fields.

  The water is simply a reflective plane.

  The sky is a gradient pigment with a wrinkle pattern at the lowest levels.
