The script creates a cut out in a given mass that is aligned with the position of the sun, as well as cutting out walls around the opening to create a space. The cut out can be any 2D shape - consequently, the script allows for the generation of openings that range in shape from simple to very complex.
The original 3D shape and the 2D shape are chosen manually, and the altitude and azimuth of the sun can be defined using the control panel of the script.
