Detailed Description

VTK data source for OCC shapes polygonal data.

Constructor & Destructor Documentation

IVtkTools_ShapeDataSource::IVtkTools_ShapeDataSource ( )

protected

Shape wrapper used as an input.

virtual IVtkTools_ShapeDataSource::~IVtkTools_ShapeDataSource ( )

protectedvirtual

Shape wrapper used as an input.

Member Function Documentation

Standard_Boolean IVtkTools_ShapeDataSource::Contains

(

const IVtkOCC_Shape::Handle &

theOccShape

)

const

Checks if the internal OccShape pointer is the same the argument.

Parameters

[in]

shape

OccShape pointer to be checked.

Returns

true if the two OccShape instances are the same, and false otherwise.

void IVtkTools_ShapeDataSource::FastTransformModeOff ( )

inline

Set the source OCCT shape.

Parameters

theOccShape

[in] OCCT shape wrapper.

void IVtkTools_ShapeDataSource::FastTransformModeOn ( )

inline

Set the source OCCT shape.

Parameters

theOccShape

[in] OCCT shape wrapper.

IVtk_IdType IVtkTools_ShapeDataSource::GetId

(

)

const

Returns ID of the shape used as a topological input for this data source.

Returns

requested ID.

const IVtkOCC_Shape::Handle& IVtkTools_ShapeDataSource::GetShape ( )

inline

Get the source OCCT shape.

Returns

occShape OCCT shape wrapper.

virtual int IVtkTools_ShapeDataSource::RequestData ( vtkInformation *  theRequest, vtkInformationVector **  theInputVector, vtkInformationVector *  theOutputVector  )

overrideprotectedvirtual

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

theRequest	[in] information about data object. In current implementation it is ignored.
theInputVector	[in] the input data. As adata source is the start stage of the VTK pipeline, theInputVector is empty and not used (no input port).
theOutputVector	[in] the pointer to output data, that is filled in this method.

void IVtkTools_ShapeDataSource::SetShape

(

const IVtkOCC_Shape::Handle &

theOccShape

)

Set the source OCCT shape.

Parameters

theOccShape

[in] OCCT shape wrapper.

vtkSmartPointer<vtkIdTypeArray> IVtkTools_ShapeDataSource::SubShapeIDs

(

)

Access to the shape's sub-shape ids array.

Returns

the array cast to vtkIdTypeArray

vtkSmartPointer<vtkPolyData> IVtkTools_ShapeDataSource::transform ( vtkPolyData *  theSource, const gp_Trsf &  theTrsf  ) const

protected

Transforms the passed polygonal data by the given OCCT transformation matrix.

Parameters

theSource	[in] source polygonal data to transform.
theTrsf	[in] transformation to apply.

Returns

resulting polygonal data (transformed copy of source).

protected

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.

Standard_Boolean IVtkTools_ShapeDataSource::myIsTransformOnly

protected

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.

IVtkOCC_Shape::Handle IVtkTools_ShapeDataSource::myOccShape

protected

Shape wrapper used as an input.

IVtkVTK_ShapeData::Handle IVtkTools_ShapeDataSource::myPolyData

protected

Polygonal representation of shape.
