[Radiance-general] mkillum to produce zero radiance (sealing geometry)

[Lars O. Grobe]

Hi List!

I have a scene containing to modifiers that should be converted to 
illums by mkillum. The first, called illum, should be the actual light 
source for indirect calculation. That is well documented with mkillum. 
The second is to "seal" geometry only. That means, the modified 
surfaces are so small, that I can neglect them to reduce the number of 
light sources in the indirect calculation. RwR chapter 13.1 suggests to 
seal such geometry with zero-radiance illums, but doesn't propose how 
to set them. So that is the point where I am, can I somehow give this 
zero-radiance as an option to mkillum?

Thank You, CU Lars.
