	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 vector field weight curves.

Author: Tanner Finken; Josh A. Levine

Date: 2024.

This filter takes a 2D vector field as input and computes the number of pairs as a function of weight (i.e. the number of pairs whose simplification weight is higher than a threshold).

These curves provide useful visual clues in order to fine-tune simplification thresholds of a discrete vector field.

Parameters

Input	Input Vector Field
Output	Table giving the number of all simplified pairs as a function of weight(simplifying value) (vtkTable)
