[Radiance-general] rtcontrib problems

[Ji Zhang]

Sorry, just figured out that the source for Problem 2: the "-fo" option
should be added in addition to the "-ffc" and "-f" options

the script should be:

vwrays -ff -x 600 -y 600 -vf ./views/back.vf \
|rtcontrib -ab 3 -ad 4096 -ar 256 -aa .1 -lw 0.0003 -n 2 \
-fo -ffc `vwrays -d -x 600 -y 600 -vf ./views/back.vf` -f tregenza.cal -b
tbin \
-o ./patches_copy/p%03d.hdr -m sky_glow -w \
./testroom_whitesky.oct
