I am working on a facade for my architecture class and I am trying to figure out a way to be able to control the middle points along a series of lines in order to create dynamic shapes and have control of where the line intersection points are. All three rows of points are currently based on 3 separate curves that follow the same shape (20 feet apart from one another). I am aiming for a design that would allow me to have random waves, but also wanting to study the look of a sine wave. This is eventually going to be a screen system made up of rectangular hollow metal bars so if anyone knows how I can go about placing those shapes along the lines, I would also appreciate that advice!
