| Abstract: | A simple and convenient algorithm for the inverse calculation of the controlling points of the triple B spline curve and surface is resented. It is suitable for the inverse calculation of quasi uniform and non uniform B spline curve and surface. By adopting non knot boundary conditions, so not necessary to be provided by user, it makes the process of inverse calculation simplified. |
