A rational cubic spline, with shape control parameters, has been discussed here with the view to its application in computer graphics. It incorporates both conic sections and parametric cubic curves as special cases. An efficient scheme is presented ...

Arc splines are G^1 continuous curves made of circular arcs and straight-line segments. They have the advantages that the curvature of an arc spline is known and controlled at all but a finite number of points, and that the offset curve of an arc spline ...

We present a flexible, stable and locally adjustable conic blending method for the sparse points interpolation, which can avoid the potential pitfalls and unacceptable cases appeared in the circular blending method. Two interpolatory schemes are ...
