Gendaylits dky discretization

Hi all, I hope you are doing well.
I am relatively new to Radiance and trying to use Radiance add-on for Blender VI-Suite for my master’s thesis in irradiance analysis of partially shaded solar modules. So my apologies beforehand if my question is too obvious.

I would like to know whether “gendaylit” function discretize the generated Perez sky to patches? I couldn’t find any information about it in the manual.

Hi Chingiz,

Welcome to the Radiance Forum!

The Perez sky model used by gendaylit is continuous, similar to the gensky command. If you need patches, you can pass the output to genskyvec, which will produce a set of Tregenza or Reinhart patches based on the -M option setting. Did you find the man pages for these commands and look at those?


Hello Mr. Ward.
Thanks for the answer.

Yes I found the manual pages and go through them.
