* @brief extract a subset from a vtkDataSet.
|
||
|
|
*
|
||
|
|
* vtkExtractSelection extracts some subset of cells and points from
|
||
|
|
* its input dataset. The dataset is given on its first input port.
|
||
|
|
* The subset is described by the contents of the vtkSelection on its
|
||
|
|
* second input port. Depending on the content of the vtkSelection,
|
||
|
|
* this will use either a vtkExtractSelectedIds, vtkExtractSelectedFrustum
|
||
|
|
* vtkExtractSelectedLocations or a vtkExtractSelectedThreshold to perform
|
||
|
|
* the extraction.
