Btw, this is to control arrays with bezier curves, in case someone is interested. Does anyone know a general formula for bezier curves of the xth order?
It's explained in http://en.wikipedia.org/wiki/B%C3%A9zier_curve
But by far, the most common are order 2 (Tcl/Tk, TrueType, etc) and order 3 (Illustrator, PDF, etc) and there's a reason for that. They become increasing complicated and hard to handle as the order increases, and I don't mean the computation time : even though computation time does increase a lot with the order, it's not as radical as the decrease of your ability to figure out the parameters to make the curve go where you want it to go, because it looks less predictable.
So, usually, when they have more than four dots, people chain together pieces made from three or four dots each.
