def smoothed(mesh, angle):
    '''
    Return a non- watertight version of the mesh which will
    render nicely with smooth shading. 

    Arguments
    ---------
    mesh:  Trimesh object
    angle: float, angle in radians, adjacent faces which have normals
           below this angle will be smoothed.

    Returns
    ---------
    smooth: Trimesh object
