	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 overlap between labeled vtkPointSets.

Author: Jonas Lukasczyk jl@jl.nosp@m.uk.d.nosp@m.e

Date: 01.09.2018

VTK wrapping code for the ttk::TrackingFromOverlap package.

This filter identifies and tracks labeled vtkPointSets across time (and optionally levels) based on spatial overlap, where two points overlap iff their corresponding coordinates are equal. This filter can be executed iteratively and can generate nested tracking graphs.

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.

Parameters

Input	A vtkMultiBlockDataSet that holds the labeled vtkPointSets and has one of the following forms: {t_0,...,t_n} or {l_0:{t_0,...,t_n}, ... , l_m:{t_0,...,t_n}} where t_i is the vtkPointSet of timestep i, and l_j is a vtkMultiBlockDataSet that holds all timesteps of level j.
Output	A vtkUnstructuredGrid that represents the (nested) tracking graph embedded in the spatial domain.
