[Radiance-general] rad program

[Jia Hu]

Hello,

I checked the rad. It has a good feature. But I am a little confused with
several variable settings

*rad* [ *-s* ][ *-n|-N* *npr* ][ *-t* ][ *-e* ][ *-V* ][ *-w* ][ *-v* *view*][
*-o* *device* ]  *rfile* [ *VAR=value* *..*  ]

(1) is that right the option [-v view] and "view" variable in .rif have the
same function?

(2)  For three sets (1) "OCTREE", (2)"scene" (3) "object" and "materials" ,
if I change files in "object" and "material", will .oct be updated when I
run "rad -t sample.rif" ?  Similarly, if I change files indicated in
"scene", the oct. will be updated even if "OCTREE" is not changed?

Cheers,
Jia
