            CREATE SCENE DESCRIPTION MARKERS FOR
                 AMBIENT SAMPLING LOCATIONS

This script puts coloured markers (spheres) at points where hemispherical
sampling was initiated.  The locations and levels are taken from the binary
ambient file.  The levels are colour coded -

       Level 0 = red
       Level 1 = green
       Level 2 = blue
       Level 3 = yellow
       Level 4 = cyan
       Level 5 = magenta
       Level 6 = pink 

To view the locations, include the file "amb_pos.rad" when re-creating
the octree.
