BRepTools_TrsfModification Class Reference

Describes a modification that uses a gp_Trsf to
change the geometry of a shape. All functions return
true and transform the geometry of the shape.

	BRepTools_TrsfModification (const gp_Trsf &T)
gp_Trsf &	Trsf ()
	Provides access to the gp_Trsf associated with this modification. The transformation can be changed.
Standard_Boolean	NewSurface (const TopoDS_Face &F, Handle< Geom_Surface > &S, TopLoc_Location &L, Standard_Real &Tol, Standard_Boolean &RevWires, Standard_Boolean &RevFace)
	Returns true if the face F has been modified. If the face has been modified:
Standard_Boolean	NewCurve (const TopoDS_Edge &E, Handle< Geom_Curve > &C, TopLoc_Location &L, Standard_Real &Tol)
	Returns true if the edge E has been modified. If the edge has been modified:
Standard_Boolean	NewPoint (const TopoDS_Vertex &V, gp_Pnt &P, Standard_Real &Tol)
	Returns true if the vertex V has been modified. If the vertex has been modified:
Standard_Boolean	NewCurve2d (const TopoDS_Edge &E, const TopoDS_Face &F, const TopoDS_Edge &NewE, const TopoDS_Face &NewF, Handle< Geom2d_Curve > &C, Standard_Real &Tol)
	Returns true if the edge E has a new curve on surface on the face F. If a new curve exists:
Standard_Boolean	NewParameter (const TopoDS_Vertex &V, const TopoDS_Edge &E, Standard_Real &P, Standard_Real &Tol)
	Returns true if the Vertex V has a new parameter on the edge E. If a new parameter exists:
GeomAbs_Shape	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)
	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>).

		Handle< Geom_Curve > &	C,
		TopLoc_Location &	L,
		Standard_Real &	Tol
	)		[virtual]

• 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.

		const TopoDS_Edge &	NewE,
		const TopoDS_Face &	NewF,
		Handle< Geom2d_Curve > &	C,
		Standard_Real &	Tol
	)		[virtual]

• 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.

		const TopoDS_Edge &	E,
		Standard_Real &	P,
		Standard_Real &	Tol
	)		[virtual]

• 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.

Standard_Boolean BRepTools_TrsfModification::NewPoint	(	const TopoDS_Vertex &	V,
		gp_Pnt &	P,
		Standard_Real &	Tol
	)		[virtual]

• 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.
  

Implements BRepTools_Modification.

Reimplemented in ShapeCustom_TrsfModification.

Standard_Boolean BRepTools_TrsfModification::NewSurface	(	const TopoDS_Face &	F,
		Handle< Geom_Surface > &	S,
		TopLoc_Location &	L,
		Standard_Real &	Tol,
		Standard_Boolean &	RevWires,
		Standard_Boolean &	RevFace
	)		[virtual]

• 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.
