* @brief extract point or cell data over time (parallel)
|
||
|
|
*
|
||
|
|
* vtkPExtractArraysOverTime is a parallelized version of
|
||
|
|
* vtkExtractArraysOverTime.
|
||
|
|
* vtkExtractArraysOverTime extract point or cell data given a selection. For
|
||
|
|
* every cell or point extracted, vtkExtractArraysOverTime create a vtkTable
|
||
|
|
* that is placed in an appropriately named block in an output multi-block
|
||
|
|
* dataset. For global-id based selections or location based selections, it's
|
||
|
|
* possible that over time the cell/point moves across processes. This filter
|
||
|
|
* ensures that such extractions spread across processes are combined correctly
|
||
|
|
* into a single vtkTable.
|
||
|
|
* This filter produces a valid output on the root node alone, all other nodes,
|
||
|
|
* simply have empty multi-block dataset with number of blocks matching the root
|
||
|
|
* (to ensure that all processes have the same structure).
