Are B-spline basis functions also B-splines?

92 Views Asked by At

When you write a spline curve as a linear combination of b-spline basis functions, it's called a "b-spline". The basis functions are generated recursively by the deBoor-Cox algorithm, starting with degree zero and working upwards to higher degrees. These b-spline basis functions are thus written in terms of (i.e., as a linear combination of) other b-spline basis functions, so they are also b-splines?

"B" in b-splines stands for basis. Unfortunately many people incorrectly refer to other splines (=piecewise-polynomials) as b-splines, and to b-splines as "basis b-splines" or "b-spline basis functions". Do not become one of those people :)
