Abstract: The regulation convex B ¨ | zie surface, B-spline surfaces and NURBS surfaces (BBN surface) a control point, the variation of surface shape by the BBN decomposed into a convex curved surface and has a special shape of the surface superimposed, before and after the establishment of surface deformation geometry and deformation of some quantitative relationship between displacement, has been lost convex surface BBN sufficient condition for convexity and criteria, and the corresponding results can be applied to adjust the surface shape and control algorithm design BBN .
