Abstract
This paper proposes a method to construct an G3 cubic spline curve from any given open control polygon. For any two inner Bézier points on each edge of a control polygon, we can define each Bézier junction point such that the spline curve is G2-continuous. Then by suitably choosing the inner Bézier points, we can construct a global G3 spline curve. The curvature combs and curvature plots show the advantage of the G3 cubic spline curve in contrast with the traditional C2 cubic spline curve.
