This paper presents a new algorithm to compute the degree-raised version of a spline. The new algorithm is as fast as the best existing algorithm, but is much easier to understand and to implement. The new control vertices of the degree-raised spline are obtained simply by a series of knot insertions followed by a series of knot deletions.
