摘要
Using Bezier curves of degree n + 1 as design curves XA(t) on one plane and Bezier curves of degree n + m + 1 as adjoint curves XB(t) on another parallel plane, the conditions of constructing developable surfaces of degree (n+ 1, n + m+ 1) are discussed.These conditions are determined by the control vextexes of the two Bezier curves and the matching functions. Furthermore, the methods for constructing developable surface of degree (n + 1, n + 2) and compositive surfaces are derived.
