Load Open3D Mesh
================

Demonstrates loading mesh models from open3d.

.. GENERATED FROM PYTHON SOURCE LINES 9-16

.. warning::
    An external model is needed to run this example.

To run this example, you need a model from the source repo's example
folder. If you are running this example from a local copy of the code (dev
install) no further actions are needed. Otherwise, you may have to replace
the path below to point to the location of the model.

Once the path is set correctly, you can use the model as follows:
