[Radiance-general] Re: Simulating Real Skies

[Mark Stock]

I don't know if this is directly useful, but I implemented some 
of the Preetham, Shirley, Smits model for sky color and radiance 
as a .cal file and gensky replacement. In addition (using the 
libnova library) the sun, moon, bright planets, and starfield can 
be placed properly (though the brightness of the starfield isn't 
yet perfectly accurate).
