int | checkEmptyMPIInput (inputType *input) |
| This method tests whether the input is a nullptr. If the computation is being done on multiple processes, it is possible that the domain of one process or more is empty, but not others, therefore in that particular case the rest of the filter will not be computed but an error message will not be sent.

- Parameters
-
Input | Input scalar field, defined as a point data scalar field attached to a geometry, either 2D or 3D, either regular grid or triangulation (vtkDataSet) |
Output0 | Output critical points (vtkPolyData) |
Output1 | Output 1-separatrices (vtkPolyData) |
Output2 | Output 2-separatrices (vtkPolyData) |
Output3 | Output data segmentation (vtkDataSet) |
The input data array needs to be specified via the standard VTK call vtkAlgorithm::SetInputArrayToProcess() with the following parameters:
- Parameters
-
idx | 0 (FIXED: the first array the algorithm requires) |
port | 0 (FIXED: first port) |
connection | 0 (FIXED: first connection) |
fieldAssociation | 0 (FIXED: point data) |
arrayName | (DYNAMIC: string identifier of the input array) |
The optional offset array can be specified via the standard VTK call vtkAlgorithm::SetInputArrayToProcess() with the following parameters:
- Parameters
-
idx | 1 (FIXED: the second array the algorithm requires) |
port | 0 (FIXED: first port) |
connection | 0 (FIXED: first connection) |
fieldAssociation | 0 (FIXED: point data) |
arrayName | (DYNAMIC: string identifier of the offset array) |
- Note
- : To use this optional array,
ForceInputOffsetScalarField
needs to be enabled with the setter ‘setForceInputOffsetScalarField()’.
This filter can be used as any other VTK filter (for instance, by using the sequence of calls SetInputData(), Update(), GetOutput()).
See the related ParaView example state files for usage examples within a VTK pipeline.
