I m investigating building an online simulation experience for students which has them using (under cloud license) Rhino with the LB/HB suite of tools. In such circumstances, being able to run on a Mac and Windows platform is of paramount importance. I am aware that the basic tools such as Rhino 6, Open Studio and Radiance work on the Mac. Of course, Daysim only has a Windows installer. As it happens, so does the Human UI menu system I am exploring to deliver the VPL Scripts to students. With its removal from official sources (Daysim 4.0 ) may well be going out of fashion. This has me looking more closely at Honeybee+, whose Daylight analyses are as far as I can see only dependent on Radiance. Bu t there I encounter scripts and example files with incomplete Python scripts and that are also in need of careful updating. The grid based version I have seems to fall over at the crucial data visualisation / analysis time AND takes 10 times longer than the DAYSIM based analysis.
