Automatic window shade inclination to block the direct sunlight

It’s possible to do this but you’d be modeling each of the blind states with detailed geometries, which can be pretty time consuming. I imagine that most Radiance modelers would try to account for this with BSDF files to represent the venetian blinds. I think we are close to releasing a three-phase recipe, though @mikkel knows more about this than I right now.

You can run the annual-daylight (2-phase) simulation with detailed geometry for each blind state. There is no blinds post-processing in Grasshopper yet, but there is a workaround as highlighted here.

However, the 3-phase method is suited for this kind of analysis. The recipe has been in the background while working on annual-daylight with aperture groups and post-processing. But I believe it is ready (or almost ready) to be pushed to Grasshopper. The only issue is again that there is no way of post-processing states in Grasshopper - maybe we should push for this sooner rather than later (cc: @chris).
