DAYLIGHT FACTOR CALCULATION |
| 21 |
|
| 22 |
This script calculates daylight factors and/or illuminance levels on a |

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. |
