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 the computation of an approximation of a persistence diagram.

Parameters

Output

The output of this filter is composed of:

The approximation of the persistence diagram (VTU).
The corresponding approximation of the scalar field (VTI).
Uncertainty boumds on the correct localization of persistence pairs.

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

Date: 2022.

This filter computes an approximation of the persistence diagram of the extremum-saddle pairs of an input scalar field. The approximation comes with a user-controlled error on the relative Bottleneck distance to the exact diagram.

Parameters

Input Input scalar field, either 2D or 3D. Must be a regular grid.
