Computing Mesh Quality
~~~~~~~~~~~~~~~~~~~~~~
Leverage powerful VTK algorithms for computing mesh quality.
Here we will use the :func:`pyvista.DataSetFilters.compute_cell_quality` filter
to compute the cell qualities. For a full list of the various quality metrics
available, please refer to the documentation for that filter.
