Camera and Light
================

To render a picture, you need to add one or multiple camera and light objects
to the scene. This guide explains how to add and move (within) them.

.. literalinclude:: ../../../../../examples/blender/docs/rendering.py
   :language: python
   :start-after: [camera-light]
   :end-before: [camera-light]

.. image:: camera-light.png

As you see, our camera and light are not well oriented yet. We can fix this with the function :py:func:`~ddg.visualization.blender.object.look_at_point`. (See :ref:`blender_orientation`)

.. literalinclude:: ../../../../../examples/blender/docs/rendering.py
   :language: python
   :start-after: [orient]
   :end-before: [orient]
