[Radiance-general] IES files and MGF geometry

[Christopher Rush]

Do I understand that the problem is not generating geometry much taller than the actual lens, but rather that that it generates a cylinder with top and bottom circles, while only the shell of the cylinder is the actual light emitter? I had started to reply regarding adjusting the height in the IES file, but maybe someone else knows a solution for the top/bottom surface problem - which would be good to know.

The product I'm looking at is this:

which is why I want to get rid of the top and bottom bits of the
ies2rad geometry.

What I was hoping to be able to do with MGF is tell it what the
fitting looks like.  In this particular case, I'd model 3 stacked
cylinders, enclosed with a disk at the top. Only the middle cylinder
would act as an emitter.  Does that make sense?

Best
Axel
