Radiance and co

   Dear OSArch members,

   I know Dion is a Radiance expert. Is there somebody here (other than Dion :-)) to write some words on Light Simulation (measurements for DIN or other technical Standard qualification).

   I use Dialux (which is fighting for BIM support, I told them to look here for help) and Relux (which sells a Revit Plug-In as BIM support) to plan luminaries into buildings at my work here in Esslingen. Luminaries have different file formats (uld or rolf for those two software tools, or ies, eulumdat and iesXML?). There is a ies support inside Blender (last activity 2018,https://developer.blender.org/D1543). There used to be a VI-Suite that integrates Radiance into Blender which would do the job. But VI-Suite 0.6 is still not official, the installation is for programmers. I never had a deeper look into Radiance.

   First steps would help my move to FOSS tools for that purpose.

   Thanks

   Lukas

   At this time only vi-suite 0.4 version package with installer are available (blender 2.79 based if i recall correctly) .

   Honeybee is next on the to-do list for the Ladybug + Blender port. That would help provide users the ability to do light analysis.

   Note that IES support in Blender unfortunately doesn't help much for light simulation, as Blender does not produce photometric output.
