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 for smoothing meshes on surfaces.

Author: Pierre Guillou pierr.nosp@m.e.gu.nosp@m.illou.nosp@m.@lip.nosp@m.6.fr

Date: March 2022.

ttk::GeometrySmoother with a twist! This class smoothes and projects a 1D or a 2D mesh onto a 2D closed triangulated surface.

Parameters

Input	vtkDataSet
Output	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 mask 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 mask array)

Note: : To use this optional array, ForceInputMaskScalarField needs to be enabled with the setter ‘setForceInputMaskScalarField()’.

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