[Radiance-general] RE: Sun Color

[Marcus Jacobs]

Thanks Martin and Greg for the help for my question about the sun color.


I have done some light research on of the sun's color temperature. I think 
Martin's may be the method that I would prefer in converting a color 
temperature and luminance of the sun to the RGB used with the light 
primative. I have had some problems running the script. In a comment line it 
states:


converts a color temperature of degrees Kelvin into RGB given: color temp. T 
and the luminance YL of the source


My problem is that this script takes three variables (T, YL, and 
solar_radiance) but the comment only mentions two variables (T and YL). What 
is the solar_radiance and how does it differ from the luminance of the 
source (the source I am assuming is the sun)? Also, what are the units of 
measurement for the 3 variables? Do you have an example for this?

Thanks

Marcus Jacobs
