[Radiance-general] Plug-in ies FILE

[Lars O. Grobe]

There is a tool called ies2rad included in radiance, which will 
translate a ies-formatted distribution to a light source in Radiance. 
The process is also described well in RwR, or in the various tutorials. 
Still, you must be careful - the orientation of some ies-distributions 
seams to be a cause for errors frequently, and you also have to make 
sure that the units in the ies-file fit those in the scene (or the 
translation corrects this). It is good practice to place the light 
source, after the translation, using !xform-statements - that way you 
can easily change them.

CU Lars.
