摘要
提出了一种局部延拓NURBS曲线的算法。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。
An algorithm is presented for locally extending NURBS curves. 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.
