An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

Constructor & Destructor Documentation

◆ GeomFill_BoundWithSurf()

GeomFill_BoundWithSurf::GeomFill_BoundWithSurf	(	const Adaptor3d_CurveOnSurface &	CurveOnSurf,
		const double	Tol3d,
		const double	Tolang )

Constructs a boundary object defined by the 3d curve CurveOnSurf. The surface to be filled along this boundary will be in the tolerance range defined by Tol3d. What's more, at each point of CurveOnSurf, the angle between the normal to the surface to be filled along this boundary, and the normal to the surface on which CurveOnSurf lies, must not be greater than TolAng. This object is to be used as a boundary for a GeomFill_ConstrainedFilling framework. Warning CurveOnSurf is an adapted curve, that is, an object which is an interface between:

the services provided by a curve lying on a surface from the package Geom
and those required of the curve by the computation algorithm which uses it. The adapted curve is created in the following way: occ::handle<Geom_Surface> mySurface = ... ; occ::handle<Geom2d_Curve> myParamCurve = ... ; // where myParamCurve is a 2D curve in the parametric space of the surface mySurface occ::handle<GeomAdaptor_Surface> Surface = new GeomAdaptor_Surface(mySurface); occ::handle<Geom2dAdaptor_Curve> ParamCurve = new Geom2dAdaptor_Curve(myParamCurve); CurveOnSurf = Adaptor3d_CurveOnSurface(ParamCurve,Surface); The boundary is then constructed with the CurveOnSurf object: double Tol = ... ; double TolAng = ... ; myBoundary = GeomFill_BoundWithSurf ( CurveOnSurf, Tol, TolAng );
