In contrast to utilizing a polynomial of a higher degree, this results in a smooth interpolation that stays much closer to the target points. The interpolation is based on a t value. The t value has to be monotonically increasing. This in turn means that a regular spline can only ever go into one direction. However, parametric splines overcome this limitation.
