[Radiance-general] reflector size

[Greg Ward]

An example of how this is done is given in the ray/obj/virtual directory included with the Radiance auxiliary file distribution.  Unfortunately, I don't have time to answer further questions on this.  You'll just have to figure it out yourself.

And is there a lot of additional geometry outside of the room, like the rest of a building, or even surrounding buildings? How large is everything outside the room?
