[Radiance-general] rad

[Thomas Seebohm]

When you run the rad command the first thing it does is to call on rpict
with arguments like the following where the resolution, -x, and, -y, are 64.
The output pic image is then piped to /dev/null

rpict -vu 0 0 1 -vf ca1.vf -dp 1024 -ar 32 -ms 2.5 -ds .3 -dt .1 -dc .5 -dr
1 -sj .7 -st .1 -ab 3 -af sc5.amb -aa .15 -ad 768 -as 196 -av 0.5 0.5 0.5
-lr 6 -lw .002 -x 64 -y 64 -ps 1 sc5.oct > /dev/null

What is the purpose of this call on rpict?

The second call to rpict which does the real work following the above would
look like:

rpict -vu 0 0 1 -vf ca1.vf -x 2048 -y 1536 -ps 4 -pt .08 -dp 1024 -ar 32 -ms
2.5 -ds .3 -dt .1 -dc .5 -dr 1 -sj .7 -st .1 -ab 3 -af sc5.amb -aa .15 -ad
768 -as 196 -av 0.5 0.5 0.5 -lr 6 -lw .002 sc5.oct > sc5_ca1.unf
        pfilt -1 -e 1 -r 1 -x /2 -y /2 sc5_ca1.unf > sc5_ca1.pic
        rm -f sc5_ca1.unf
