Detailed Description

Geometric transformation on a shape. The transformation to be applied is defined as a gp_GTrsf transformation. It may be:

a transformation equivalent to a gp_Trsf transformation, the most common case: you should , however, use a BRepAPI_Transform object to perform this kind of transformation; or
an affinity, or
more generally, any type of point transformation which may be defined by a three row, four column matrix of transformation. In the last two cases, the underlying geometry of the following shapes may change:
a curve which supports an edge of the shape, or
a surface which supports a face of the shape; For example, a circle may be transformed into an ellipse when applying an affinity transformation. The transformation is applied to:
all the curves which support edges of the shape, and
all the surfaces which support faces of the shape. A GTransform object provides a framework for:
defining the geometric transformation to be applied,
implementing the transformation algorithm, and
consulting the result.

Constructor & Destructor Documentation

◆ BRepBuilderAPI_GTransform() [1/2]

BRepBuilderAPI_GTransform::BRepBuilderAPI_GTransform ( const gp_GTrsf & T )

Constructs a framework for applying the geometric transformation T to a shape. Use the function Perform to define the shape to transform.

◆ BRepBuilderAPI_GTransform() [2/2]

BRepBuilderAPI_GTransform::BRepBuilderAPI_GTransform	(	const TopoDS_Shape &	S,
		const gp_GTrsf &	T,
		const Standard_Boolean	Copy = `Standard_False`
	)

Constructs a framework for applying the geometric transformation T to a shape, and applies it to the shape S.

If the transformation T is direct and isometric (i.e. if the determinant of the vectorial part of T is equal to 1.), and if Copy equals false (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: the constructed framework can be reused to apply the same geometric transformation to other shapes: just specify them with the function Perform.

Member Function Documentation

◆ Modified()

virtual const TopTools_ListOfShape& BRepBuilderAPI_GTransform::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_GTransform::ModifiedShape ( const TopoDS_Shape & S ) const

overridevirtual

Returns the modified shape corresponding to <S>.

Reimplemented from BRepBuilderAPI_ModifyShape.

◆ Perform()

void BRepBuilderAPI_GTransform::Perform	(	const TopoDS_Shape &	S,
		const Standard_Boolean	Copy = `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 (i.e. if the determinant of the vectorial part of T is equal to 1.), and if Copy equals false (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: just specify them by calling the function Perform again.
