◆ Continuity()

GeomAbs_Shape BRepTools_TrsfModification::Continuity ( const TopoDS_Edge & E,
const TopoDS_Face & F1,
const TopoDS_Face & F2,
const TopoDS_Edge & NewE,
const TopoDS_Face & NewF1,
const TopoDS_Face & NewF2 )
overridevirtual

Returns the continuity of <NewE> between <NewF1> and <NewF2>.

<NewE> is the new edge created from <E>. <NewF1> (resp. <NewF2>) is the new face created from <F1> (resp. <F2>).

Implements BRepTools_Modification.

◆ IsCopyMesh()

Standard_Boolean & BRepTools_TrsfModification::IsCopyMesh ( )

Sets a flag to indicate the need to copy mesh.

◆ NewCurve()

Standard_Boolean BRepTools_TrsfModification::NewCurve ( const TopoDS_Edge & E,
Handle< Geom_Curve > & C,
TopLoc_Location & L,
Standard_Real & Tol )
overridevirtual

Returns true if the edge E has been modified. If the edge has been modified:

  • C is the new geometric support of the edge,
  • L is the new location, and
  • Tol is the new tolerance. If the edge has not been modified, this function returns false, and the values of C, L and Tol are not significant.

Implements BRepTools_Modification.

Reimplemented in ShapeCustom_TrsfModification.

◆ NewCurve2d()

Standard_Boolean BRepTools_TrsfModification::NewCurve2d ( const TopoDS_Edge & E,
const TopoDS_Face & F,
const TopoDS_Edge & NewE,
const TopoDS_Face & NewF,
Handle< Geom2d_Curve > & C,
Standard_Real & Tol )
overridevirtual

Returns true if the edge E has a new curve on surface on the face F. If a new curve exists:

  • C is the new geometric support of the edge,
  • L is the new location, and
  • Tol the new tolerance. If no new curve exists, this function returns false, and the values of C, L and Tol are not significant.

Implements BRepTools_Modification.

Reimplemented in ShapeCustom_TrsfModification.

◆ NewParameter()

Standard_Boolean BRepTools_TrsfModification::NewParameter ( const TopoDS_Vertex & V,
const TopoDS_Edge & E,
Standard_Real & P,
Standard_Real & Tol )
overridevirtual

Returns true if the Vertex V has a new parameter on the edge E. If a new parameter exists:

  • P is the parameter, and
  • Tol is the new tolerance. If no new parameter exists, this function returns false, and the values of P and Tol are not significant.

Implements BRepTools_Modification.

Reimplemented in ShapeCustom_TrsfModification.

◆ NewPoint()

Standard_Boolean BRepTools_TrsfModification::NewPoint ( const TopoDS_Vertex & V,
gp_Pnt & P,
Standard_Real & Tol )
overridevirtual

Returns true if the vertex V has been modified. If the vertex has been modified:

  • P is the new geometry of the vertex, and
  • Tol is the new tolerance. If the vertex has not been modified this function returns false, and the values of P and Tol are not significant.

Reimplemented in ShapeCustom_TrsfModification.

◆ NewPolygon()

Standard_Boolean BRepTools_TrsfModification::NewPolygon ( const TopoDS_Edge & E,
Handle< Poly_Polygon3D > & P )
overridevirtual

Returns true if the edge has been modified according to changed polygon. If the edge has been modified:

  • P is a new polygon

◆ NewPolygonOnTriangulation()

Standard_Boolean BRepTools_TrsfModification::NewPolygonOnTriangulation ( const TopoDS_Edge & E,

Standard_Real & Tol,
Standard_Boolean & RevWires,
Standard_Boolean & RevFace )
overridevirtual

Returns true if the face F has been modified. If the face has been modified:

  • S is the new geometry of the face,
  • L is its new location, and
  • Tol is the new tolerance. RevWires is set to true when the modification reverses the normal of the surface (the wires have to be reversed). RevFace is set to true if the orientation of the modified face changes in the shells which contain it. For this class, RevFace returns true if the gp_Trsf associated with this modification is negative.

Standard_Boolean BRepTools_TrsfModification::NewTriangulation ( const TopoDS_Face & F,
