// .NAME vtkDuplicatePolyData - For distributed tiled displays.
|
|
// .SECTION Description
|
|
// This filter collects poly data and duplicates it on every node.
|
|
// Converts data parallel so every node has a complete copy of the data.
|
|
// The filter is used at the end of a pipeline for driving a tiled
|
|
// display.
