[Radiance-general] Examples on BRTD

[Gregory J. Ward]

Hi Yu,

Try starting from here:

	http://radsite.lbl.gov/radiance/digests_html/v2n5.1.html#BRDF

Unfortunately, Radiance does not compute indirect lighting through  
BRDF materials except for the direct component.  I am working on a  
specialty program, similar to mkillum, to handle cases where a BSDF  
material covers a window or skylight opening, but that is months away  
from completion.

Best,
-Greg
