The current Radiance measure has a few different built-in BSDF choices but I need to write a script that can take a any arbitrary user-specified BSDF XML file and run it in the Radiance engine of OpenStudio.
My planned approach is that the user-specified BSDF files would be made outside of OpenStudio (genBSDF). I would then rewrite the RadianceMeasure's measure.rb. Specifically in calculateDaylightCoeffecients I'd rewrite mapping.rad to look at a different BSDF XML (e.g. replace "blinds.xml" with "my_slats.xml" in mapping.rad). I would also of course rewrite the measure interface to ask which BSDF file the user wanted to use.
This seems workable even though I think this is kind of a work-around because on first inspection it looks like the usual BSDF files (blinds.xml, etc.) may actually be hard-coded into the OpenStudio to Radiance translation program.
Does anyone foresee any problems in using this approach?
