Eye Dome Lighting
~~~~~~~~~~~~~~~~~

Eye-Dome Lighting (EDL) is a non-photorealistic, image-based shading technique
designed to improve depth perception in scientific visualization images.
To learn more, please see `this blog post`_.

Point Cloud
+++++++++++

When plotting a simple point cloud, it can be difficult to perceive depth.
Take this Lidar point cloud for example:

.. GENERATED FROM PYTHON SOURCE LINES 25-29

.. code-block:: Python


    point_cloud = examples.download_lidar()
    point_cloud


.. GENERATED FROM PYTHON SOURCE LINES 30-31

And now plot this point cloud as-is:

.. GENERATED FROM PYTHON SOURCE LINES 31-38

.. code-block:: Python


    # Plot a typical point cloud with no EDL
    pl = pv.Plotter()
    pl.add_mesh(point_cloud, color="tan", point_size=5)
    pl.show()



.. GENERATED FROM PYTHON SOURCE LINES 39-43

We can improve the depth mapping by enabling eye dome lighting on the
renderer with :func:`pyvista.Renderer.enable_eye_dome_lighting`.

Try plotting that point cloud with Eye-Dome-Lighting yourself below:

.. GENERATED FROM PYTHON SOURCE LINES 43-50

.. code-block:: Python


    pl = pv.Plotter()
    pl.add_mesh(point_cloud, color="tan", point_size=5)
    # Turn on eye dome lighting here
    pl.show()



.. GENERATED FROM PYTHON SOURCE LINES 51-54

The eye dome lighting mode can also handle plotting scalar arrays. Try the
above block but by specifying a ``scalars`` array instead of ``color`` in
the ``add_mesh`` call.
