Parameters
----------
callback : callable
The method called every time the plane is updated. Takes two
arguments, the normal and origin of the plane in that order.
normal : str or tuple(float)
The starting normal vector of the plane
origin : tuple(float)
The starting coordinate of the center of the place
bounds : tuple(float)
Length 6 tuple of the bounding box where the widget is placed.
factor : float, optional
An inflation factor to expand on the bounds when placing
color : string or 3 item list, optional, defaults to white
Either a string, rgb list, or hex color string.
assign_to_axis : str or int
Assign the normal of the plane to be parallel with a given axis:
options are (0, 'x'), (1, 'y'), or (2, 'z').
tubing : bool
When using an implicit plane wiget, this controls whether or not
tubing is shown around the plane's boundaries.
outline_translation : bool
If ``False``, the plane widget cannot be translated and is strictly
placed at the given bounds. Only valid when using an implicit
plane.
origin_translation : bool
If ``False``, the plane widget cannot be translated by its origin
and is strictly placed at the given origin. Only valid when using
an implicit plane.
implicit : bool
When ``True``, a ``vtkImplicitPlaneWidget`` is ued and when
``False``, a ``vtkPlaneWidget`` is used.
pass_widget : bool
If true, the widget will be passed as the last argument of the
callback
test_callback: bool
if true, run the callback function after the widget is created.
