Move the mouse to change your viewpoint. This uses filled oblongs and quadrangles. The cuboid actually has a back, it's just obscured by the other faces. I had to make layer priorities, so there might be a bit of strange overlapping as you move it around, I have taken away most of it though. Change the top slider to set the pen size, 1 is glitchy. Change the bottom slider to set the cuboid size, the viewpoint doesn't work as well at bigger sizes. Press 'F'to toggle whether the cube's sides are filled in or not.
100% me. I got this idea in Art class, when we were drawing one-perspective cubes and things. This is probably the most technical project I've done, there's a lot of really long scripts for the quadrangle coords. The scripts are a bit longer than they could be, but I was lazy and made the front & back squares with only two 'true' points, the other two are worked out. The unseeable back square is actually vital to the project, as the side quadrangles use it as a reference point. The back also has a colour- dark red!
