[Radiance-general] "INDIRECE"in .rif file

[victor li]

Thank you for your reply!

It has been a while since I looked at the rad code but I'm pretty sure
that INDIRECT only affects the "-ab" value of the rpict comand.
Depending on your QUALITY setting is either INDIRECT = -ab
or INDIRECT=-ab-1. To keep the -ab value constant you have to
override it in with the "render=" option.

I am confused by the " INDIRECT = -abor INDIRECT=-ab-1. To keep the -ab
value constant you have to override it in with the "render=" option."  In my
setting, "INDIRECT would be a number, like INDIRECT = 5.

For my setting in rtrace, other ambient options are high enough to avoid the
mistake.  And the INDIRECT is est in .rif file and rtrace is set in another
file.  My setting is as following:

rtrace -I -h -dp 2046 -ar 32 -ms 0.063 -ds .2 -dt .05 -dc .75 -dr 3 -sj 1
-st .01 -ab 8 -aa .1 -ad 2048 -as 1024 -av 0.01 0.01 0.01 -lr 12 -lw .0005
-af 5.amb 5.oct < 5.pts > 5.dat

RESOLUTION= 640 480
DETAIL= MEDIUM
VARIABILITY= MEDIUM
QUALITY= MEDIUM
INDIRECT= 5
REPORT= 2

render= -i
