Detailed Description

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

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 .

Reimplemented from BRepBuilderAPI_ModifyShape.

◆ ModifiedShape()

virtual TopoDS_Shape BRepBuilderAPI_GTransform::ModifiedShape ( const TopoDS_Shape S) const
overridevirtual

Returns the modified shape corresponding to .

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.
