[Radiance-general] Predicting Patch-based diffuse Irradiance values

[sokol dervishi]

Dear All, 

I wanted to ask a question related to the prediction of the diffuse horizontal (or vertical contribution) of a particular patch of the sky ( with a specific patch altitude, solid angle, patch azimuth). 

I am developing a patch-based Irradiance model and I wanted to compare with other models in Radiance , e.g.Perez Model. I know How to calculate the diffuse horizontal, or any titled surface of the whole sky, but in my case I wanted to compare in a patch-based mode. So I need to simulate a patch-based contribution of diffuse component in horizontal or any titled surface. 

I thank you in advance, 


Regards, 

Sokol
