[Radiance-general] Modelling sky using sky scanner MS-321LR

[Lars O. Grobe]

Hi Ehsan,

as far as I understand the scan pattern used by the scanner is close 
enough to the Tregenza patches to use it with dctimestep and daylight 
coefficients. To get an idea of the format expected by that tool, have a 
look at the output of gendaylit.

Be aware that the sun is excluded in the measurements, so you will have 
to find a way to get the direct sun contribution. As there are no "color 
channels" in the measurement, you would use the luminance readings and 
apply them to all three channels in Radiance equally (R=G=B).

Cheers, Lars.
