Bézier Spline

Another way to make a curved line with very few points. named after the French mathematician Pierre Bézier (pronounced BEZ-ee-ay), these curves employ at least three points to define a curve. The two endpoints of the curve are called anchor points. The other points, which define the shape of the curve, are called handles, tangent points, or nodes. Attached to each handle are two control points. By moving the handles and the control points, you end up having a lot of control over the shape of the curve. Different from b-splines, which use control points that don't necessarily touch the curve.
