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 &	theShape,
		const gp_Trsf &	theTrsf,
		const Standard_Boolean	theCopyGeom = `Standard_False`,
		const Standard_Boolean	theCopyMesh = `Standard_False`
	)

Creates a transformation from the gp_Trsf <theTrsf>, and applies it to the shape <theShape>. If the transformation is direct and isometric (determinant = 1) and <theCopyGeom> = Standard_False, the resulting shape is <theShape> on which a new location has been set. Otherwise, the transformation is applied on a duplication of <theShape>. If <theCopyMesh> is true, the triangulation will be copied, and the copy will be assigned to the result shape.

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 &	theShape,
		const Standard_Boolean	theCopyGeom = `Standard_False`,
		const Standard_Boolean	theCopyMesh = `Standard_False`
	)

Applies 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 theCopyGeom 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 theShape.
If theCopyMesh is true, the triangulation will be copied, and the copy will be assigned to the result shape. 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.
