Convert a NumPy array to a vtkDataArray or vice versa.

Parameters:
arrnp.ndarray | vtkDataArray

A numpy array or vtkDataArray to convert.

namestr, optional

The name of the data array for VTK.

deepbool, default: False

If input is numpy array then deep copy values.

array_typeint, optional

VTK array type ID as specified in vtkType.h.

Returns:
vtkDataArray | numpy.ndarray

The converted array. If input is a numpy.ndarray then returns vtkDataArray or if input is vtkDataArray then returns NumPy ndarray.
