Computer-aided design systems often use an extended concept of a spline known as a Nonuniform rational B-spline (NURBS). If sampled data from a function or a physical object is available, spline interpolation is an approach to creating a spline that approximates that data.
A spline is a piecewise polynomial. The curve is made up of one or more pieces, where each piece is a polynomial. The polynomials are normally chosen such that they “match up” at the transitions and you end up with something that looks like a single continuous curve.

A linear spline is of course a special case of the more general polynomial spline, where the sections between knots are polynomials of degree \ (D=1\). The formula below is equivalent to the linear spline formula, but with added polynomial terms. We now have D + K + 1 parameters to estimate.
In the mathematical subfield of numerical analysis, a B-spline or basis spline is a spline function that has minimal support with respect to a given degree, smoothness, and domain partition. Any spline function of given degree can be expressed as a linear combination of B-splines of that degree.
Splines add curves together to make a continuous and irregular curves. When using this tool, each click created a new area to the line, or a line segment. Each click also creates what’s called a control point, or points that determine the shape of the curve. And that’s the gist of a spline.
The polynomials we construct are called cubic splines. In spline parlance, the interpolation points {xj}n j=0 are called knots. These cubic spine requirements can be written as: sj(xj f (xj 1), j 1, . . . , n; 1) = = sj(xj) = f (xj), j = 1, . . . , n; s0j(xj) = s0j+1(xj), j = 1, . . . , n 1; s00 j (xj) = s00 j+1(xj), j = 1, . . . , n 1.
A spline is a type of piecewise polynomial function. In mathematics, splines are often used in a type of interpolation known as spline interpolation. Spline curves are also used in computer graphics and computer-aided design (CAD) to approximate complex shapes.
• Splines can be used to define objects of any dimension – 2D surfaces – 3D solids – … • Higher dimensions are built from same 1D functions – spline patches have control points – joining patches together is more complicated than curves N2 Context 14
