Smooth Connection between Cubic Bezier Curves and Cubic B-spline Curves

Using the property that cubic B-spline curve can change into Cubic Bezier Curve,the problem of connection between cubic Bezier curves and cubic B-spline Curves is changed into another problem,connection between cubic Bezier curves,three theorems about,and continuity of connection between cubic Bezier curves and cubic B-spline Curves are given respectively in this paper.
