The luminaire manufacturers show increasing interest in 3D luminaire geometry. They do not only want to distribute their photometrics but also 3D geometry, which enables the light planner to create high quality visualizations. Most luminaire file formats define some sort of geometry. Very resticted in shape it is sometimes only luminous geometry. Only the IES format has the possibility to add high end geometry as a link to a MGF file. But this feature is very rarely used. The members of Relux now have started to assign 3D geometry files to their luminaires. The models may have various articulations and they also have proper materials. Through Relux Vision they can be exported to Radiance.
