摘　　要：利用积分方法构造了带形状参数的C-B样条曲线基函数,这类曲线具有标准C-B样条曲线主要性质,如连续性、凸包性等;根据形状参数的各种不同取值调控曲线形状,由此生成的曲线与曲面,作为一种新的几何造型方法,可应用于CAD/CAM领域。A new class of basis functions was present to construct C-B spline curves with shape parameters,This kind of curve combines the main properties of the standard C-B spline curve. The shape of such curves can be adjusted by changing the values of the shape parameters. As a new geometric modeling method,generating of such curves and surfaces can be applied in CAD/ CAM.
