WebIf each polynomial segment has degree 3, the spline is called a cubic spline. If each segment is described by its ending positions and derivatives, it is said to be in "Hermite" form. The b-spline approach gives a convenient way of ensuring continuity between segments. In fact, you can show that every spline can be represented in b-spline form.
