[Radiance-general] Measuring red, green and blue light component in certain space

[alira at gsd.harvard.edu]

Hi all,

I have modeled a cubical room (4 x 4 meters) with no windows or any type
of apertures; the room is completely closed and empty, without any kind of
objects inside. There is only a diffusive light source located in the
middle of the ceiling. My intention is to change the color and texture of
the walls, and then measure the resulting light reaching the geometrical
center of the room: 1)INTENSITY (in radiance units) and 2)the amount of
RED, GREEN and BLUE of the resulting light spectrum also in radiance
units.  How can I do these measurements?
