| Abstract: | Based on the theory of B spline,this paper discusses the sufficient and necessary conditions of G 1 continuity between two patches of bi cubic tensor product non uniform B spline surfaces in a special type,and gives a kind of sufficient condition of G 1 continuity so as to satisfy the need of application. |

| Keywords: | non uniform B spline surface non uniform B spline basis function G 1 continuity sufficient and necessary condition |
