[Radiance-general] practical question about radiance

[Christopher Rush]

Can you save the geometry of the chair in its own .rad file with an appropriate origin point at the center or corner of the chair extents? Then in your overall scene you can include as many lines as you like to repeat the chair such as:

### full scene rad file

#rest of your scene
materialname polygon name
0 0 4 ...
[other scene geometry]

# one instance of chair moved one unit in x direction
!xform -t 1 0 0 chair.rad
# another instance of chair moved one unit in y direction after rotating it 90deg
!xform -rz 90 -t 0 1 0 chair.rad
# a 2x2 array of chairs after starting 2 units in the y direction
!xform -t 0 2 0 -a 2 -t 0 1 0 -a 2 -t 1 0 0 chair.rad

#rest of scene
[other scene geometry]
