Fourier transform of the box spline, in dimensions, is given by
De Boor's algorithm, a fast and numerically stable algorithm for evaluating spline curves in B-spline form
I. J. Schoenberg gave the spline function its name after its resemblance to the mechanical spline used by draftsmen.
Deformation of the hull is based on the concept of so-called hyper-patches, which are three-dimensional analogs of parametric curves such as Bézier curves, B-splines, or NURBs.
NURBS are commonly used in computer-aided design (CAD), manufacturing (CAM), and engineering (CAE) and are part of numerous industry wide standards, such as IGES, STEP, ACIS, and PHIGS.
For screens installed on aluminium frames, the material is cut slightly larger than the frame, then laid over it, and a flexible vinyl cord, called a spline, is pressed over the screen into a groove (spline channel) in the frame.
