// .NAME vtkPolyDataStreamer - Stream appends input pieces to the output.
|
|
// .SECTION Description
|
|
// 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.
|
|
// .SECTION Note
|
|
// The output may be slightly different if the pipeline does not handle
|
|
// ghost cells properly (i.e. you might see seames between the pieces).
|
|
// .SECTION See Also
