I do a test that compare the glare values derived by 5-PM with different sun patches and the ones calculated by conventional raytracing method, and found that when the sun patches was above 1278, the error of 5-PM have no signifcant change. Thus, it is sufficient accurate to calculate the glare metric for the 5-PM with 1278 sun patches. So I want to know if some applications require scenario for 5-PM with high sun patches (MF:4/5/6).
My results are presented here, I test two complex fenestration systems, which are the micro prismatic redirection fenestration and the spcular blind.
Errors of glare metrics for PDRF
Errors of glare metrics for specular blind
