[Radiance-general] how to filter objects by modifier?

[Ian Tester]

After a problem report from Lars, here's an updated version of the filter 
script. It wasn't handling the rare alias declaration. I've tested it 
against a few scene files in the standard distribution, both 
virtual/illumoff.rad and cabin/lvfurn.rad. The second one put a spanner in 
the works because it contained this:

alberta_image alias alberta_photo
         photo_paper

So there's extra logic to handle having the reference on the following 
line. How lenient is the Radiance parser with respect to newlines? Can 
regular primitives also contain newlines in odd places, or is it just with 
aliases?

e.g
white sphere
	ball	<== is this accepted as well??
0
0
4	0	0	0
	1

I really hope that isn't allowed. Otherwise my perl code will become really 
ugly... :(

bye
