[Radiance-general] Strange results

[Lars O. Grobe]

Hi Catarina!

I would count Ecotect as one of the building simulation systems 
including an interface to Radiance. It is not a free one (unlike others, 
e.g. Openstudio, Esp-r, ...).

You may want to have a look at Livi, which is a Radiance interface for 
Blender. It looks pretty cool... Artificial lighting is handled by 
adding an IES candela distribution data block to Blender's lamp object.

Besides that it is a good idea to at least once "understand" Radiance 
without an user interface. The frontends are all nice and polished, and 
give the impression that things are easier than using text files and 
commands. But they also hide critical aspects, setting some defaults or 
making assumptions that one should at least be aware of. Take a look at 
the tutorial section at www.radiance-online.org, especially the two 
tutorials by Axel are a perfect start!

Cheers, Lars.
