变阶样条(CD-Spline)是B-Spline的直接扩展，允许不同的线段具有不同的阶数。本文给出了一种CD-Spline的升阶方法。该方法是灵活的，因为它适用于任何CD-Spline的任何段的任何程度的提升。用这种方法可以将CD-Spline变换成B-Spline，反之亦然，用这种方法可以实现不同阶的变换。此外，这种升阶方法被描述为一种拐角切割过程。
Changeable degree spline (CD-spline), a direct extension of the B-spline, allows different segments to possess different degrees. In this paper, we present a method for degree elevation of a CD-spline. The method is flexible, as it applies to any segment of any CD-spline elevated by any degree. A CD-spline can be transformed into a B-spline, and vice versa, in various orders by using this method. Moreover, this degree elevation method is presented as a corner cutting process.
