α Extension for a Class of Alternate B-type Spline Curve

摘要：

By introducing the concept of weights in NURBS curve into a blending technique, the paper extends the representation of the alternate B-type spline curve of 4-5-5-4 degree. Shape-control capability of the extension curve is shown to be much better than that of the alternate B-type spline curve. The representation and properties of the extension curve are studied. The curve is easy and intuitive to reshape by varying the parameters; so it is useful in some applications of CAD/CAM .
