[Radiance-general] Luminaire modelling using Radiance

[Thomas Bleicher]

German

Have you tried to change the geometry identifier in the IES file to
indicate a box geometry. I am a bit rusty on the specs but I don't think
anything else depends on this information so the change should be simple to
do. The transformation in a Radiance box is then done by ies2rad.

Regards,
Thomas
