然后可以在算法中直接使用该基本数据(度,周期特征,极点和权重,节点和多重性),或者可以通过调用Geom2d_BSplineCurve、Geom_BSplineCurve和Geom_BSplineSurface类提供的构造函数来构造曲线或曲面。 Geom2dConvert包提供如下: 一个全局函数,用于根据Geom2d包中的2D曲线从有界曲线构造BSpline曲线, 一种分裂算法,它计算应该...

生成的BSpline 曲线将是C2连续或者二阶连续,除非在一个点上定义了切向约束,在这种情况下,曲线会是C1连续。 这个类可以通过下面的方法实例 GeomAPI_PointsToBSplineApprox(Points,DegMin,DegMax,Continuity,Tol);Handle(Geom_BSplineCurve)K=Approx.Curve(); Surface Approximation曲面近似 GeomAPI包中的PointsToBSpline...
