Radiance is the lighting simulation package where the format comes  
from. Radiance was originally developed at LBL, but is now open  
source. There's a loose organization of researchers which work with  
and on Radiance.  You can find us at <http://www.radiance-online.org/

form, I've called us the Radiance Lighting Simulation Group.

Hmmm.

Oh, I see.  No, they just recognize the format and some of the file  
extensions; there's no problem changing the media type name.
