Standard_EXPORT | Geom2dAPI_ExtremaCurveCurve (const Handle(Geom2d_Curve)&C1, const Handle(Geom2d_Curve)&C2, const Quantity_Parameter U1min, const Quantity_Parameter U1max, const Quantity_Parameter U2min, const Quantity_Parameter U2max) |
Computes the extrema between - the portion of the curve C1 limited by the two points of parameter (U1min,U1max), and - the portion of the curve C2 limited by the two points of parameter (U2min,U2max). Warning Use the function NbExtrema to obtain the number of solutions. If this algorithm fails, NbExtrema returns 0. . | |
Standard_EXPORT Standard_Integer | NbExtrema () const |
Returns the number of extrema computed by this algorithm. Note: if this algorithm fails, NbExtrema returns 0. . | |
