Return a direction vector.

Parameters:	zdir{'x', 'y', 'z', None, 3-tuple} The direction. Possible values are: - 'x': equivalent to (1, 0, 0) - 'y': equivalent to (0, 1, 0) - 'z': equivalent to (0, 0, 1) - None: equivalent to (0, 0, 0) - an iterable (x, y, z) is returned unchanged.
Returns:	x, y, zarray-like The direction vector. This is either a numpy.array or zdir itself if zdir is already a length-3 iterable.
