| 摘 要： | 本文根据Gregory修正曲面片的方法,利用双三次Coons曲面片与双三次Bezier曲面片之间的相互关系,提出了扭矢相容性修正的双三次Bezier曲面的构造方法,从而避免了曲面片连接或插值时由于扭夫相容带来的局限性,使得复杂曲面的造型设计成为可能。

| Abstract: | Aacocding to the method of Gregory modified Surface patch, this paper puts fooward the formation method of the bicubuic Bezier pat- ches with the twisted vector Compatibility by means of the interre- lation of the bicubic Coons patch and the bicubic Bezier patch. Thus the limitations b ought by the twisted v ctor compatibility on the patches Connect on or interpolation are avo ded, which makes the moleling design of complex surface patches possible. |
