Parameters
----------
width : float
Box width.
height : float
Box height.
depth : float
Box depth.
width_segments : int
Box segments count along the width.
height_segments : float
Box segments count along the height.
depth_segments : float
Box segments count along the depth.
planes: array_like
Any combination of ``{'-x', '+x', '-y', '+y', '-z', '+z'}``
Included planes in the box construction.
vertex_colors : ndarray
Same as for `MeshVisual` class. See `create_plane` for vertex ordering.
face_colors : ndarray
Same as for `MeshVisual` class. See `create_plane` for vertex ordering.
color : Color
The `Color` to use when drawing the cube faces.
edge_color : tuple or Color
The `Color` to use when drawing the cube edges. If `None`, then no
cube edges are drawn.
