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. | |

TTK VTK-filter for eigenfunctions computation.
This plugin computes the first eigenfunctions of a given triangular surface mesh.
Input0 | Input 2D geometry, either regular grid or triangulation (vtkDataSet) |
Output | Output eigenfunctions (vtkDataSet) |
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.
