Also, how did you compute the dispersion coefficients? The original was 1.4+50.0/(w-230), but I curvefit this to Sellmeier. Coefficients are A=1, B0=0.940608, C0=0.061544, B1=0.220931, C1=0.061271, B2=-30.611816, C2=-262.595686, in case you’re interested.

]]>Your work was always top notch.

]]>Great Stuff! I have been trying to implement the Preetham model myself.

I have a question though: how did you compute the sun radiance (and converted appropriately to “color space”)?

Keep those nice renders coming

Cheers
