In the mathematical field of numerical analysis and in computer graphics a Bézier spline's a spline curve where each polynomial of the spline's in Bézier form. In other words, a Bézier spline's simply a series of Bézier curves stacked end to end where the last point of one curve coincides with the starting point of the next curve. Definition Given a spline S of degree n with k knots xi we can write the spline as a Bézier spline as: S(x) := left\right.… (More on Bezigon)
