	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 efficiently computes the contour tree of scalar data and more (data segmentation, topological simplification, persistence diagrams, persistence curves, etc.).

Author: Guillaume Favelier guill.nosp@m.aume.nosp@m..fave.nosp@m.lier.nosp@m.@lip6.nosp@m..fr.; Julien Tierny julie.nosp@m.n.ti.nosp@m.erny@.nosp@m.lip6.nosp@m..fr

Date: February 2016

This filter takes a scalar field attached as point data to a geometry (either 2D or 3D, either regular grids or triangulations) and computes its contour tree. Several outputs are produced to encode the nodes of the tree (as points in 3D space), the arcs of the tree and the data segmentation.

Parameters

Input	Input scalar field, either 2D or 3D, either regular grid or triangulation (vtkDataSet)
Output0	Output nodes (vtkPolyData)
Output1	Output arcs (vtkPolyData)
Output2	Output data segmentation (vtkUnstructuredGrid)
Output3	Output persistence diagram (vtkUnstructuredGrid)
Output4	Output persistence curve (vtkUnstructuredGrid)

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.
