BRepBuilderAPI_Transform Class Reference

Geometric transformation on a shape.
The transformation to be applied is defined as a
gp_Trsf transformation, i.e. a transformation which does
not modify the underlying geometry of shapes.
The transformation is applied to:

	BRepBuilderAPI_Transform (const gp_Trsf &T)
	Constructs a framework for applying the geometric transformation T to a shape. Use the function Perform to define the shape to transform.
	BRepBuilderAPI_Transform (const TopoDS_Shape &S, const gp_Trsf &T, const Standard_Boolean Copy=Standard_False)
	Creates a transformation from the gp_Trsf <T>, and applies it to the shape <S>. If the transformation is direct and isometric (determinant = 1) and <Copy> = Standard_False, the resulting shape is <S> on which a new location has been set. Otherwise, the transformation is applied on a duplication of <S>.
void	Perform (const TopoDS_Shape &S, const Standard_Boolean Copy=Standard_False)
	pplies the geometric transformation defined at the time of construction of this framework to the shape S.
virtual const TopoDS_Shape &	ModifiedShape (const TopoDS_Shape &S) const
	Returns the modified shape corresponding to <S>.
virtual const TopTools_ListOfShape &	Modified (const TopoDS_Shape &S)
	Returns the list of shapes modified from the shape <S>.

Detailed Description

• all curves which support edges of a shape, and
  
• all surfaces which support its faces.
  A Transform object provides a framework for:
  
• defining the geometric transformation to be applied,
  
• implementing the transformation algorithm, and
  
• consulting the results.

	)

• If the transformation T is direct and isometric, in
  other words, if the determinant of the vectorial part
  of T is equal to 1., and if Copy equals false (the
  default value), the resulting shape is the same as
  the original but with a new location assigned to it.
  
• In all other cases, the transformation is applied to a duplicate of S.
  Use the function Shape to access the result.
  Note: this framework can be reused to apply the same
  geometric transformation to other shapes. You only
  need to specify them by calling the function Perform again.
