The Wolfram Language supports state-of-the-art splines for use both in graphics and computational applications. The Wolfram Language allows not just cubic splines, but splines of any degree—for curves, surfaces, and in general manifolds of any dimension. The Wolfram Language can not only handle and import splines numerically, but can also represent them as explicit piecewise symbolic functions, fully integrated with all the Wolfram Language's computational functionality.
