class  Geom2dConvert_BSplineCurveKnotSplitting
 An algorithm to determine points at which a BSpline curve should be split in order to obtain arcs of the same continuity. If you require curves with a minimum continuity for your computation, it is useful to know the points between which an arc has a continuity of a given order. The continuity order is given at the construction time. For a BSpline curve, the discontinuities are localized at the knot values. Between two knot values the BSpline is infinitely and continuously differentiable. At a given knot, the continuity is equal to: Degree - Mult, where Degree is the degree of the BSpline curve and Mult is the multiplicity of the knot. It is possible to compute the arcs which correspond to this splitting using the global function SplitBSplineCurve provided by the package Geom2dConvert. A BSplineCurveKnotSplitting object provides a framework for: More...
