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.

Detailed Description

TTK VTK-filter that wraps the discreteVectorField processing package.

Author: Tanner Finken finke.nosp@m.nt@a.nosp@m.rizon.nosp@m.a.ed.nosp@m.u; Joshua A. Levine josh@.nosp@m.cs.a.nosp@m.rizon.nosp@m.a.ed.nosp@m.u

Date: May 2024.

VTK wrapping code for the ttk::dcvf::DiscreteVectorField package.

IEEE Vis 2024.

Parameters

Input	Input vector field (vtkDataSet)
Output	Output glyphs (vtkPolyData)

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)

This filter can be used as any other VTK filter (for instance, by using the sequence of calls SetInputData(), Update(), GetOutput()).
