Conclusion

We have constructed appropriate B₂-spline blending functions for construction of spline-blended (Gordon) surface. We have also constructed system of spline curves containing appropriate interpolation curve and B-spline curve. The interpolation curve is just special case of B₂- spline curve, but we have found appropriate odd controll points. User does not have to take care of them, but they can also be changed using parameter p. The results of this paper were implemented and we represent them in several pictures below.
