20     DAYLIGHT FACTOR CALCULATION
21    
22     This script calculates daylight factors and/or illuminance levels on a
23     rectangular workplane and produces a contour plot from the result. The
24     input is a Radiance scene description (and octree) and the output is one
25     or more color Radiance pictures.
