摘要
依据有关 B样条理论 ,研究了一种特定类型的双三次张量积非均匀 B样条曲面间 G2 光滑拼接的充要条件 ,且给出了此种类型的两张双三次张量积非均匀 B样条曲面间 G2光滑拼接的一种充分条件 。
According to the theory of B spline,this paper discusses the sufficient and necessary conditions of G\+2 continuity between two patches of bi cubic tensor product non uniform B spline surfaces in a special type,meanwhile,in order to satisfy the needs of application,a special kind of sufficient conditions of G\+2 continuity is given in this paper.
