Abstract: This paper analyzes the structure of B-Spline Curve with local shape adjustment parameters,proposes the method of using transformation matrix with adjustment parameters to generate the control points,and then obtains the method of the objective Cubic B-Spline Curve with shape parameter.The study explores the influence of parameter change on the curve and the continuity conditions for generating Spline Curve at the splice point.

Key words: Cubic B-Spline Curve, adjustment parameters, matrix transformation
