双三次张量积非均匀B样条曲面G2光滑条件
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
以满足实际应用的需要
Abstract
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.
