	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 the computation of mesh subdivisions (without vertex displacement).

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

Date: December 2015.

Parameters

Input	Input mesh (vtkUnstructuredGrid)
Output	Output mesh (vtkUnstructuredGrid)

This filter subdivides an input mesh with a strategy inspired by Discrete Morse theory. It does not modify the position of the original vertices.

The filter inserts a new vertex at the barycenter of each d-cell C and connects it with an edge to the new vertices inserted in the (d-1) and (d+1)-cells that are faces or co-faces of C.

In practice, for surface meshes, this subdivision scheme corresponds to a Catmull-Clark subdivision (without vertex displacement). It will turn a triangle-mesh into a quad mesh, a quad mesh into a (finer) quad-mesh, a tetrahedral mesh into a hexahedral mesh, a hexahedral mesh into a (finer) hexadrehal mesh, etc. Generally, it will turn any 2D mesh into a quad mesh and any 3D mesh into a hexadrehal mesh.

This filter assumes that all the cells of the input mesh are of the same type. Also, the filter creates duplicate points, to be merged after the fact with "Clean to Grid" under ParaView or vtkMergePoints for instance.

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.
