class BoundWithSurf from GeomFill inherits Boundary from GeomFill
|
|
|
|
---Purpose: Defines a 3d curve as a boundary for a
|
|
-- GeomFill_ConstrainedFilling algorithm.
|
|
-- This curve is attached to an existing surface.
|
|
-- Defines a constrained boundary for filling
|
|
-- the computations are done with a CurveOnSurf and a
|
|
-- normals field defined by the normalized normal to
|
|
-- the surface along the PCurve.

|
returns mutable BoundWithSurf from GeomFill;
|
|
---Purpose:
|
|
-- 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:
|
|
-- Handle(Geom_Surface) mySurface = ... ;
|
|
-- Handle(Geom2d_Curve) myParamCurve = ... ;
|
|
-- // where myParamCurve is a 2D curve in the parametric space of the surface mySurface
|
|
-- Handle(GeomAdaptor_HSurface)
|
|
-- Surface = new
|
|
-- GeomAdaptor_HSurface(mySurface);
|
|
-- Handle(Geom2dAdaptor_HCurve)
|
|
-- ParamCurve = new
|
|
-- Geom2dAdaptor_HCurve(myParamCurve);
|
|
-- CurveOnSurf = Adaptor3d_CurveOnSurface(ParamCurve,Surface);
|
|
-- The boundary is then constructed with the CurveOnSurf object:
|
|
-- Standard_Real Tol = ... ;
|
|
-- Standard_Real TolAng = ... ;
|
|
-- myBoundary = GeomFill_BoundWithSurf (
|
|
-- CurveOnSurf, Tol, TolAng );
