Public Member Functions
	vtkTypeMacro (IVtkTools_ShapeDataSource, vtkPolyDataAlgorithm) static IVtkTools_ShapeDataSource *New()
Initialization
Set the source OCCT shape. Parameters [in] theOccShape OCCT shape wrapper.
void	SetShape (const IVtkOCC_Shape::Handle &theOccShape)
	Get the source OCCT shape.
const IVtkOCC_Shape::Handle &	GetShape ()
	Get the source OCCT shape.
void	FastTransformModeOn ()
	Get the source OCCT shape.
void	FastTransformModeOff ()
	Get the source OCCT shape.
Data accessors
Returns ID of the shape used as a topological input for this data source. Returns requested ID.
IVtk_IdType	GetId () const
	Checks if the internal OccShape pointer is the same the argument.
bool	Contains (const IVtkOCC_Shape::Handle &theOccShape) const
	Checks if the internal OccShape pointer is the same the argument.
vtkSmartPointer< vtkIdTypeArray >	SubShapeIDs ()
	Access to the shape's sub-shape ids array.

Protected Member Functions
Interface to override
This is called by the superclass. This is the method you should override if you use this class as ancestor. Build output polygonal data set from the shape wrapper. Parameters [in] theRequest information about data object. In current implementation it is ignored. [in] theInputVector the input data. As adata source is the start stage of the VTK pipeline, theInputVector is empty and not used (no input port). [in] theOutputVector the pointer to output data, that is filled in this method.
int	RequestData (vtkInformation *theRequest, vtkInformationVector **theInputVector, vtkInformationVector *theOutputVector) override

Internals
Transforms the passed polygonal data by the given OCCT transformation matrix. Parameters [in] theSource source polygonal data to transform. [in] theTrsf transformation to apply. Returns resulting polygonal data (transformed copy of source).
IVtkOCC_Shape::Handle	myOccShape
	Shape wrapper used as an input.
IVtkVTK_ShapeData::Handle	myPolyData
	Polygonal representation of shape.
bool	myIsFastTransformMode
	Indicates whether light-weighted processing for transformed shapes is enabled. If so, data source does not re-compute the discrete model for the input topological shape. It rather uses the already existing one and applies the necessary transformation to it.
bool	myIsTransformOnly
	Internal flag indicating that the current working shape is just a transformed copy of the previously processed one. This flag is used in a couple with "fast transformation" mode flag.
vtkSmartPointer< vtkPolyData >	transform (vtkPolyData *theSource, const gp_Trsf &theTrsf) const
	Shape wrapper used as an input.
	IVtkTools_ShapeDataSource ()
	Shape wrapper used as an input.
	~IVtkTools_ShapeDataSource () override
	Shape wrapper used as an input.
