Detailed Description

Stream appends input pieces to the output.

Date:

2001/10/11 13:37:11

Revision:

1.8

vtkPolyDataStreamer initiates streaming by requesting pieces from its single input it appends these pieces it 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

vtkPolyDataStreamer* vtkPolyDataStreamer::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkPolyDataSource.

virtual const char* vtkPolyDataStreamer::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter.

int vtkPolyDataStreamer::IsTypeOf (  const char *    type )  [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 vtkPolyDataToPolyDataFilter.

virtual int vtkPolyDataStreamer::IsA (  const char *    type )  [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 vtkPolyDataToPolyDataFilter.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter.

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 vtkSource.

void vtkPolyDataStreamer::SetNumberOfStreamDivisions (  int    num )

Set the number of pieces to divide the problem into.

virtual int vtkPolyDataStreamer::GetNumberOfStreamDivisions (    )  [virtual]

Set the number of pieces to divide the problem into.

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.

void vtkPolyDataStreamer::Execute (    )  [protected, virtual]

This method is the old style execute method Reimplemented from vtkSource.

void vtkPolyDataStreamer::ComputeInputUpdateExtents (  vtkDataObject *    output )  [protected, virtual]

What is the input update extent that is required to produce the desired output? By default, the whole input is always required but this is overridden in many subclasses. Reimplemented from vtkPolyDataSource.
