Load Open3D Pointcloud
======================

Demonstrates loading pointclouds from open3d.

.. 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.
