Known quantity of sides and vertices. I wouldn't even cry if they wanted me to provide all eight of the (x,y) coordinates!! A circle is a simple enough formula of (x,y,z) where (x,y) == center and z == radius or diameter as long as its standard. I can say by how much to move things in a for loop for 360 frames with a 1 degree change per frame. But why is there no Fluffle Puffing software that can do this TI-BASIC level processing?
