I'm trying to animate a polygon plane so that it follows a predetermined path, namely a spiral shape (the idea is to have two spirals to wind round eachother and create a DNA helix). The original position shouldn't move, the plane is supposed to 'grow' into the spiral. I'm kinda at a loss as to how to accomplish this. I guess it is possible to use curves somehow? Or model a spiral and have the animated plane sort of snap to it as it scales (warp deformer?)? I've no experience in this, do you guys have any suggestions?
