static BSplineRestriction()
  • Returns a new shape with all surfaces, curves and pcurves which type is BSpline/Bezier or based on them converted having Degree less than <MaxDegree> or number of spans less than <NbMaxSegment> in dependence on parameter priority <Degree>. <GmaxDegree> and <GMaxSegments> are maximum possible degree and number of spans correspondingly. These values will be used in those cases when approximation with specified parameters is impossible and one of GmaxDegree or GMaxSegments is selected in dependence on priority. Note that even if approximation is impossible with <GMaxDegree> then number of spans can exceed specified <GMaxSegment> <Rational> specifies if to convert Rational BSpline/Bezier into polynomial B-Spline. If flags ConvOffSurf,ConvOffCurve3d,ConvOffCurve2d are Standard_True there are means that Offset surfaces , Offset curves 3d and Offset curves 2d are converted to BSPline correspondingly.
