For this module, I decided to have four separate surfaces rather than one single surface, largely due to the way my module 3 project constructed its initial surfaces. For the 2- and 3-units portions, I enabled the user to choose four images to place on the four surfaces of the structure, and I allowed for transposition and reversal of those images as desired, as well as embossing or debossing based on color brightness. I will note that I had to change the transposition section, as I needed to change the way the image was sampled to get a good transposed image over this long and thin of a structure. Pictured here are an image of a bus, an image of a train, the test color stripe image, and da Vinci’s The Last Supper.
For the 4-unit portion, I kept the default red-to-blue color scheme for representing sun incidence, with red representing higher sun incidence and blue representing lesser sun incidence. I also had the panels’ wall thickness parameters set by sun incidence, and as such the panels facing the sun have smaller openings than the panels facing away from the sun. This is again separated into each of the four surfaces, so that each one can be controlled individually to some degree if desired.
