[Radiance-general] Antimatter

[Greg Ward]

Hi Rob,

I'm not able to reproduce this error with the latest version of  
Radiance.  What version are you running?  Is anyone getting my e-mails?

Jack's example runs fine, and if you add a floor:

void plastic gray
0
0
5 .2 .2 .2 0 0

!genbox gray floor 10 10 .1 | xform -t 0 0 -.1001

...you get to see the shadows through the windows.  I also tried using  
"void" instead of "red" as the first antimatter modifier and that  
works, as does making the wall infinitely thin (single surface), so I  
think you must be running version 3.8 or your cut-out surfaces are  
coincident or something...

The thing that doesn't work is using a non-void material as the first  
antimatter argument to cut a hole in a single-surface wall.

Cheers,
-Greg
