Curve refinement moves the other control points near the new one to preserve the shape of the curve. As you add more knots, the control points get closer and closer to the actual curve. 5Take a quick look back at the piecewise Bézier knot vector – you’ll see k knots in a row on either end, and the curve has C0 discontinuities there. name the three types of global winds
