Hi specialists,
I am a new PhD student in lighting and a beginner in Radiance. I plan to use Radiance to do some simulation calculations, but I am unsure about my parameter setting. I write them below.
Illuminance calculation:
rtrace -I -n 8 -af /Users/kevinbian/Desktop/1Simulation/ProcessFile/10X10inter.txt -ab 50 -as 1024 -lr 50 -ar 64 -lw 0 -dp 1024 -ds 0.02 -dc 1 -dj 0 -dr 6 -dt 0 -st 1 -ad 256 /Users/kevinbian/Desktop/1Simulation/ProcessFile/10X10.oct </Users/kevinbian/Desktop/1Simulation/ProcessFile/6illuminanceList/Allpoint.dat >/Users/kevinbian/Desktop/1Simulation/ProcessFile/illuminanceOut.dat
Luminance calculation:
rtrace -n 8 -af /Users/kevinbian/Desktop/1Simulation/ProcessFile/10X10inter.txt -ab 50 -as 1024 -lr 50 -ar 64 -lw 0 -dp 1024 -ds 0.02 -dc 1 -dj 0 -dr 6 -dt 0 -st 1 -ad 256 /Users/kevinbian/Desktop/1Simulation/ProcessFile/10X10.oct </Users/kevinbian/Desktop/1Simulation/ProcessFile/LumiancePointin.dat >/Users/kevinbian/Desktop/1Simulation/ProcessFile/LuminanceOut.dat
Some basic information:
My simulation environment is a 1313*3 square room, and the reflections are 0.2, 0.5, and 0.7 for the floor, wall and ceiling, respectively.
*The light source will be converted from the IES file.
*My purpose is only for calculation, not the rendering.
*I run the software on the MAC system, M1 core.
Moreover, I compare illumination results between our Radiance and AGI32. They are close, but I have no idea of how to examine my luminance result. I found that when I put a lighting source in the centre of the ceiling, there will be little difference of about 0.2-0.5 cd/m^2 in luminance in the different directions wall. Is this normal?
Is my setting correct? Please give me some help. Thanks a lot! ^^
