Detailed Description

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:

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.

Constructor & Destructor Documentation

◆ BRepBuilderAPI_Transform() [1/2]

BRepBuilderAPI_Transform::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() [2/2]

BRepBuilderAPI_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>.

Member Function Documentation

◆ Modified()

virtual const TopTools_ListOfShape& BRepBuilderAPI_Transform::Modified ( const TopoDS_Shape & S )

overridevirtual

Returns the list of shapes modified from the shape <S>.

Reimplemented from BRepBuilderAPI_ModifyShape.

◆ ModifiedShape()

virtual TopoDS_Shape BRepBuilderAPI_Transform::ModifiedShape ( const TopoDS_Shape & S ) const

overridevirtual

Returns the modified shape corresponding to <S>.

Reimplemented from BRepBuilderAPI_ModifyShape.

◆ Perform()

void BRepBuilderAPI_Transform::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.

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.
