Detailed Description

Streamer appends input pieces to the output.

vtkPolyDataStreamer initiates streaming by requesting pieces from its single input it appends these pieces to the requested output. Note that since vtkPolyDataStreamer uses an append filter, all the polygons generated have to be kept in memory before rendering. If these do not fit in the memory, it is possible to make the vtkPolyDataMapper stream. Since the mapper will render each piece separately, all the polygons do not have to stored in memory.

Attention:

The output may be slightly different if the pipeline does not handle ghost cells properly (i.e. you might see seames between the pieces).

Member Function Documentation

static vtkPolyDataStreamer* vtkPolyDataStreamer::New ( )

static

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

virtual const char* vtkPolyDataStreamer::GetClassName ( )

virtual

Reimplemented from vtkStreamerBase.

static int vtkPolyDataStreamer::IsTypeOf ( const char *  name )

static

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkStreamerBase.

virtual int vtkPolyDataStreamer::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkStreamerBase.

static vtkPolyDataStreamer* vtkPolyDataStreamer::SafeDownCast ( vtkObject *  o )

static

Reimplemented from vtkStreamerBase.

void vtkPolyDataStreamer::PrintSelf ( ostream &  os, vtkIndent  indent  )

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkStreamerBase.

void vtkPolyDataStreamer::SetNumberOfStreamDivisions

(

int

num

)

Set the number of pieces to divide the problem into.

int vtkPolyDataStreamer::GetNumberOfStreamDivisions ( )

inline

Set the number of pieces to divide the problem into.

Definition at line 54 of file vtkPolyDataStreamer.h.

virtual void vtkPolyDataStreamer::SetColorByPiece ( int  )

virtual

By default, this option is off. When it is on, cell scalars are generated based on which piece they are in.

virtual int vtkPolyDataStreamer::GetColorByPiece ( )

virtual

By default, this option is off. When it is on, cell scalars are generated based on which piece they are in.

virtual void vtkPolyDataStreamer::ColorByPieceOn ( )

virtual

By default, this option is off. When it is on, cell scalars are generated based on which piece they are in.

virtual void vtkPolyDataStreamer::ColorByPieceOff ( )

virtual

By default, this option is off. When it is on, cell scalars are generated based on which piece they are in.

virtual int vtkPolyDataStreamer::FillOutputPortInformation ( int  port, vtkInformation *  info  )

protectedvirtual

Fill the output port information objects for this algorithm. This is invoked by the first call to GetOutputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkAlgorithm.

virtual int vtkPolyDataStreamer::FillInputPortInformation ( int  port, vtkInformation *  info  )

protectedvirtual

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkAlgorithm.

int vtkPolyDataStreamer::RequestUpdateExtent ( vtkInformation *  , vtkInformationVector **  , vtkInformationVector *    )

protectedvirtual

This is called by the superclass. This is the method you should override.

Implements vtkStreamerBase.

virtual int vtkPolyDataStreamer::ExecutePass ( vtkInformationVector **  inputVector, vtkInformationVector *  outputVector  )

protectedvirtual

Implements vtkStreamerBase.

virtual int vtkPolyDataStreamer::PostExecute ( vtkInformationVector **  inputVector, vtkInformationVector *  outputVector  )

protectedvirtual

Reimplemented from vtkStreamerBase.
