That depends on time of day, of course, the Altitude and Azimuth of the sun. Mesh Shadow is very useful for this. LadyBug requires at least one external file.
I have no insights to offer about solar radiation, sorry. Looks like you did a good job with shadows, which I seem to have broken somehow… I was playing around with Mesh Shadow which basically produces outlines of the shadow areas. In the process, I tried a few things.
Used Solid Union on the stack of boxes so I have only one shadow instead of one for each box.
Added a cyan group to “ignore first and last” points on the sun path, as they seemed to cause problems.
Added optional Plane Normal …
Hello, I am working on a project where we create a kinetic facade ,which is consists by many pieces, and I want the pieces to rotate accordingly to the sun movement.
I have created the sun path but I dont know how to connect the pieces rotation with the sun (maybe as an attractor?). The facade movement (the pieces actually) is manually at the moment.
