[Radiance-general] gensky

[Jia Hu]

Hello all:

I have some questions relating to gensky command.

(1) The book of "Rendering with radiance" says luminous efficacy is set to
179 for all CIE sky models. Is that true for current version?

(2) If I know Solar direct radiation and diffuse radiation, I hope to use
Perez's (source: Modeling daylight availability and irradiance components
from direct and global irradiance, 1990 solar energy) models (that is,
interpolate two CIE sky model according to radiation), is that possible to
generate a new sky luminance distribution model by interpolation of two
standard CIE model in Radiance in order to calculate the interior
illuminance more accurately?

Thank you,.

Jia
