Non-Uniform Cubic B-Spline Curve with Given Tangent Polygon

Graphical Abstract

Abstract

Abstract

An algorithm for constructing closed and shape preserving non-uniform cubic B-spline curve with given tangent polygon is presented. The algorithm for constructing （m ＋1）th degree B-spline curve with Cm continuity is given too. Practical example illustrates that the constructed curve approximates the tangent polygon quite well.
