CIE version in gensky

Dear All,

I have a lazy question, what is the latest version of CIE sky used in
gensky at the moment? their latest update was in 2002 (CIE GENERAL SKY
STANDARD DEFINING LUMINANCE DISTRIBUTIONS) if I am correct.

Cheers,
Ehsan

Hi Ehsan,

The gensky command has overcast and clear sky distributions based on an older CIE standard. I don't remember which one, but gensky was written in the late 80's. Subsequently in 1991 or so, I added an "intermediate" sky type, but I'm not sure it adheres to the newer 2002 standard.

Most people who care about the sky distribution using gendaylit, but if enough people really want it, I could see about updating gensky to the current CIE standard(s).

Cheers,
-Greg

Hi Dr. Ward,

I will happy to have latest version of sky model. I know it is time consuming to program and update the gensky but as its part of my research work, I'll be glad if I can take part in updating it.

Cheers,
Ehsan

Zack Rogers developed a module for Python (IES_gensky.py) that is part of
SPOT and updates the gensky model.

I also seem to remember that in one of the early Radiance workshops there
was a reference to an updated CIE sky generator that could produce all 15
standard sky models. I don't think it ever got a public release but the
source files were exchenged off-list now and then.

Hi Thomas,

Thank you for the information. I don't have problem with implementing it in
MATLAB or something, but thought would be good to have latest CIE in
gensky. I will do my best to do a comparison of current gensky with the
latest CIE model to see if there is a significant improvement in prediction
or not. if so, why not to update the gensky.

Cheers,
Ehsan

Hi,

I missed that thread, so a late reply. While having the current CIE skies in gensky would certainly nice, we do not really depend on it. Philip Greenup had the models implemented in a little cal-file (ssldlum.cal), which used to be on www.radiance-online.org in the patches-directory but disappeared with the installation of the new web-site.

Still, the file is documented on page 251 of Philip's thesis (a highly recommended reading, not only that one page..). For a quick pragmatic problem-solving copy&paste will do: http://eprints.qut.edu.au/15936/1/Philip_Greenup_Thesis.pdf

Cheers, Lars.

The old radiance websites still exist, if you know how to get to them:
http://radsite.lbl.gov/radiance/
https://www.radiance-online.org:447/
Your browser will probably complain about the security of the second one,
and if you have an overzealous IT department you might not be able to use
port 447
