Hey Mark,
Any chance you could post a short summary/manpage for genutahsky? I got it compiled here, but dunno how to play with it beyond changing site and time parameters. Should I read the Pretham Shirley paper, your C source, or what? WHAT?

Rob,
The command-line options that work are basically just those: the mandatory time arguments (with a new year argument "-y 2009"), the optional location (-a -o and -m), and turbidity (-t).
The program writes a complete sky description that should probably be redirected to a file. For example:
genutahsky 10 31 13EDT -y 2009 -a 42.36 -o 71.06 -t 3 > sky.rad
generates the sky above me right now. Then you can generate your octree as normal:
oconv sky.rad scene.rad > scene.oct
Make sure that all of the ancilliary files (stardome.rad, TychoSkymap...hdr, *.cal) are put into either the current working directory or wherever the library files are.

OK, cool. THe only one I hadn't played with was turbidity. So, it's pretty much plug-and-play then? Cool! I did some skies with the sun really low and the sky dome color shifted but not as dramatically as I had expected. I'll play some more. Very cool Mark, thanks!
