What is the difference between B-spline curve, B-spline basis and B-spline function? I have thought that: a B-spline basis is a basis for B-spline function while a B-spline curve is a linear combination of B-spline basis functions ($N_{k}^{m}(t)$) s.t: $P(t)=\sum_{k=0}^{L}P_k N_{k}^{m}(t)$.
Is it all right what I have said or not?
