[Radiance-general] Rendering each matrix with 3 and 5 phase

[Taoning Wang]

Hi Thanyalak,

For you second try with rfluxmtx, I think you are missing the output image
dimensions, try:
vwrays -vf Reference1.vf -ff -x 500 -y 500 | rfluxmtx -v -x 500 -y 500 -ffc
-ab 1 -ad 65536 -lw 2e-5 -o {youroutputpath}/%03d.hdr - windowfluxmtx.rad
-i Referencerender_rflux.oct

thanks,
Taoning
