class SimpleBound from GeomFill inherits Boundary from GeomFill
---Purpose: Defines a 3d curve as a boundary for a
-- GeomFill_ConstrainedFilling algorithm.
-- This curve is unattached to an existing surface.D
uses
Pnt from gp,
Vec from gp,
Function from Law,
HCurve from Adaptor3d
is
Create(Curve : HCurve from Adaptor3d;
Tol3d : Real from Standard;
Tolang : Real from Standard)
returns mutable SimpleBound from GeomFill;
--- Purpose:
-- Constructs the boundary object defined by the 3d curve.
-- The surface to be built along this boundary will be in the
-- tolerance range defined by Tol3d.
-- This object is to be used as a boundary for a
-- GeomFill_ConstrainedFilling framework.
-- Dummy is initialized but has no function in this class.
-- Warning
-- Curve is an adapted curve, that is, an object which is an interface between:
-- - the services provided by a 3D curve from the package Geom
-- - and those required of the curve by the computation
-- algorithm which uses it.
-- The adapted curve is created in one of the following ways:
-- - First sequence:
-- Handle(Geom_Curve) myCurve = ... ;
-- Handle(GeomAdaptor_HCurve)
-- Curve = new
-- GeomAdaptor_HCurve(myCurve);
-- - Second sequence:
-- // Step 1
-- Handle(Geom_Curve) myCurve = ... ;
-- GeomAdaptor_Curve Crv (myCurve);
-- // Step 2
-- Handle(GeomAdaptor_HCurve)
-- Curve = new
-- GeomAdaptor_HCurve(Crv);
-- You use the second part of this sequence if you already
-- have the adapted curve Crv.
-- The boundary is then constructed with the Curve object:
-- Standard_Real Tol = ... ;
-- Standard_Real dummy = 0. ;
-- myBoundary = GeomFill_SimpleBound
-- (Curve,Tol,dummy);
