Former versions development

Extension uses various tools and libraries for graphical user interface and calculation.

All daylighting calculations are performed with validated Radiance software. The Radiance executables were compiled by NREL (Radiance 5.4) and LBNL-ETA (Radiance 6.1) and are included in the extension. The authors would like to thank Greg Ward and the Radiance community for their help and guidance over the past 15 years.
Authors want to thank numerous Sketchup plugins' developers from SketchUcation forums for help on various Ruby API and other extensions' related questions. The idea for surfaces higlighting comes from the extension Ruby Console+ .
