| Abstract: | According to the theory of B-spline,this paper presents a practical sufficient condition of G1 continuity for two adjacent NURBS surfaces with arbitrary degrees and single interior knots.Meanwhile,a useful algorithm is constructed.For two given NURBS surfaces,we adjust the control points and the weights nearby the common boundary curve to cause G1 continuity between them. |
