* @brief extract cells within a dataset that
|
||
|
|
* contain the locations listen in the vtkSelection.
|
||
|
|
*
|
||
|
|
* vtkExtractSelectedLocations extracts all cells whose volume contain at least
|
||
|
|
* one point listed in the LOCATIONS content of the vtkSelection. This filter
|
||
|
|
* adds a scalar array called vtkOriginalCellIds that says what input cell
|
||
|
|
* produced each output cell. This is an example of a Pedigree ID which helps
|
||
|
|
* to trace back results.
