延应

从理论上探讨了使NURBS曲线获得曲率连续的延拓应满足的条件，同时又给出了在实际应用中使NURBS曲线获得曲率连续的延拓的基本算法。

It is discussed that condition NURBS curves should satisfy in theory when it is extended with curvature continuity , and a basic principle is given to get the NURBS curve 's extended section satisfying curvature continuity practically .
