	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 computes the Jacobi set of a bivariate volumetric data-set.

Author: Julien Tierny julie.nosp@m.n.ti.nosp@m.erny@.nosp@m.lip6.nosp@m..fr

Date: May 2015.

Given a bivariate scalar field defined on a PL 3-manifold, this filter produces the list of Jacobi edges (each entry is a pair given by the edge identifier and the Jacobi edge type).

The input bivariate data must be provided as two independent scalar fields attached as point data to the input geometry.

Parameters

Input	Input bivariate volumetric data (vtkDataSet)
Output	Output Jacobi set (vtkDataSet)

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

The input data arrays needs to be specified via the standard VTK call vtkAlgorithm::SetInputArrayToProcess() with the following parameters:

Parameters

idx	0 for the U Component, 1 for the V Component
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 arrays can be specified via the standard VTK call vtkAlgorithm::SetInputArrayToProcess() with the following parameters:

Parameters

idx	2 for the U Offset Field, 3 for the V Offset Field
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()’.

See the related ParaView example state files for usage examples within a VTK pipeline.
