Wrong rotation function parameters correction.

[zyuanbing]

Thanks for the release.
I followed the instructions to compile the code, and try to reproduce the GIF showed in profile. When I ran

python teaser_python_3dsmooth.py

there was a bug:

TypeError: rotate(): incompatible function arguments. The following argument types are supported:
    1. (self: open3d.open3d_pybind.geometry.Geometry3D, R: numpy.ndarray[float64[3, 3]], center: numpy.ndarray[float64[3, 1]]) -> open3d.open3d_pybind.geometry.Geometry3D

Invoked with: geometry::TriangleMesh with 102 points and 200 triangles., array([[ 0.99154181, -0.09292577, -0.09060704],
       [-0.09292577, -0.02092779, -0.99545308],
       [ 0.09060704,  0.99545308, -0.02938598]]); kwargs: center=True

It might be wrong parameter. Perhaps it should be coordinate origin (0, 0, 0). I'm not very sure if correcting it this way would cause a new problem, but it works for me, maybe try it.

@zyuanbing Thanks!

It looks like this is due to Open3D changing their function signature after updating to 0.12.

This causes issue #99 with Open3D 0.9. If you revert this commit then everything works.

@tpwrules Thanks for the feedback. I will add an explicit comment saying that Open3D 0.9 will have issue with this example.
