I’m trying to use vwrays with rtrace and save floating-point output rather than RGBE images to calculate irradiance or illuminance. The code I’m using is:
vwrays -ff -vf Vista.vf -x 2048 -y 2048 > ./Render/04-IImagen$azimuth-$elevation-vwrays.txt rtrace -ov 02-Escena.oct < ./Render/04-IImagen$azimuth-$elevation-vwrays.txt > ./Render/04-IImagen$azimuth-$elevation.out
Nevertheless, the .out file is empty (it only has the header) and I don’t know if there is something that I’m doing wrong because I don’t really understand what I’m doing.
Could you help me with that?
Thank you in advance
