"""
Create mesh in VTK to show grain boundaries as feature edges.
Create VTK unstructured grid containing grain boundaries.
Parameters
----------
periodic : Boolean, optional
periodic : bool, optional
Show boundaries across periodicity. Defaults to True.
direction : string
Show grain boundaries only across a certain direction. ['x','y','z']
direction : string, optional
Directions to consider ('x','y','z'). Defaults to 'xyz'.
