This package draws uniform, cubic Bspline curves, open and closed, based on a sequence of Bspline control points. There is also code which permits drawing the open or closed cubic Bspline curve interplating a sequence of points.

\subsection{Closed (periodic) case}
We turn now to the periodic uniform B-spline curve interpolating $n$ points $S_0$,...,$S_{n-1}$. Extend the sequence periodically with period $n$, so that $S_n=S_0$, $S_{n+1}=S_1$, $S_{-1}=S_{n-1}$, and so on. In order to find the periodic control points $B_k$, we have to solve the $n$ equations
