[Radiance-general] IES file manipulation

[Mark de la Fuente]

Hi everyone,
 
I have a situation where I'm using ies2rad to bring files into
radiance.  Only I want to attach the photometric info to illum surfaces
surrounding my detailed fixture geometry rather than to the default
geometry...  (pretty typical I think) However in order to do so, I have
to add rectangles in order to "seal" my fixture.  I am concerned that
the addition of these rectangles will affect the magnitude of the
photometric information.
 
I guess one way to not even deal with boxing the luminaire with illums
is to attach a negative value to the lamp's glow material.  Then rays
won't "sneak out".  Of course the lamps won't add internal illumination
in that case.
 
Any thoughts would be appreciated.  I will try and run some tests when
I get a chance.
 
Thanks.
 
Mark
