[Radiance-general] sky models and color gradients

[Reinhart, Christoph]

I am very interested in a colored sky model as well Mark. Thank-you for
offering to share! This work would be a perfect topic to present at the
Radiance workshop in November. FYI, 3ds Max Design already has the Utah
sky model implemented. It generates really impressive sunsets.

I am interested in this, too. How best to make it work? Convert 
the formulae in the paper to a .cal file (that modifies a mist 
volume or a dome-like source?) Pre-render a sky dome? Modify the 
Radiance source itself?

Since it is unlikely that one of us has the extra classes to make 
the authors' sample code work, I volunteer to share what I come 
up with if I get done first.
