Splines
Mathematica supports state-of-the-art splines for use both in graphics and computational applications. Mathematica allows not just cubic splines, but splines of any degree—for curves, surfaces, and in general manifolds of any dimension. Mathematica can not only handle and import splines numerically, but can also represent them as explicit piecewise symbolic functions, fully integrated with all Mathematica's computational functionality.
Spline Objects
BezierFunction create a function representing a Bézier manifold in any dimension
BSplineFunction create a function representing a B-spline manifold in any dimension
Basis Functions
BernsteinBasis, BSplineBasis numeric or symbolic spline basis functions
Spline Interpolation
Interpolation create interpolations using splines and other methods
    
Graphics Primitives
BezierCurve 2D or 3D composite Bézier curves of any degree
BSplineCurve 2D or 3D B-spline (NURB) curves of any degree
BSplineSurface B-spline (NURB) surfaces of any degree
    
Import and Export
Import, Export import and export splines for fonts, CAD, computer graphics, etc.
