pst-bspline – Draw cu­bic Bs­pline curves and in­ter­po­la­tions

The pack­age draws uni­form, cu­bic B-spline curves, open and closed, based on a se­quence of B-spline con­trol points. There is also code which per­mits draw­ing the open or closed cu­bic Bs­pline curve in­ter­po­lat­ing a se­quence of points.
Graph­i­cal out­put is cre­ated us­ing PStricks.
