==============================
Timeline and setting keyframes
==============================

In his tutorial, you will learn how to use Fury ``Timeline`` for playing the
animations.

.. GENERATED FROM PYTHON SOURCE LINES 11-18

What is ``Timeline``?
=====================

``Timeline`` is responsible for handling the playback of Fury Animations.

``Timeline`` has playback methods such as ``play``, ``pause``, ``stop``, ...
which can be used to control the animation.

.. GENERATED FROM PYTHON SOURCE LINES 18-25

.. code-block:: Python



    import numpy as np

    from fury import actor, window
    from fury.animation import Animation, Timeline








.. GENERATED FROM PYTHON SOURCE LINES 26-27

We create our ``Scene`` and ``ShowManager`` as usual.

.. GENERATED FROM PYTHON SOURCE LINES 27-32

.. code-block:: Python

    scene = window.Scene()

    showm = window.ShowManager(scene, size=(900, 768))
    showm.initialize()








.. GENERATED FROM PYTHON SOURCE LINES 33-38

Creating a ``Timeline``
=======================

FURY ``Timeline`` has the option to attaches a very useful panel for
controlling the animation by setting ``playback_panel=True``.

.. GENERATED FROM PYTHON SOURCE LINES 40-41

Creating a ``Timeline`` with a PlaybackPanel.

.. GENERATED FROM PYTHON SOURCE LINES 41-43

.. code-block:: Python

    timeline = Timeline(playback_panel=True)








.. GENERATED FROM PYTHON SOURCE LINES 44-45

Creating a Fury Animation as usual

.. GENERATED FROM PYTHON SOURCE LINES 45-52

.. code-block:: Python

    anim = Animation()
    sphere = actor.sphere(np.zeros([1, 3]), np.ones([1, 3]))
    anim.add_actor(sphere)
    # Now that the actor is add to the ``Animation``, setting keyframes to the
    # Animation will animate the actor accordingly.









.. GENERATED FROM PYTHON SOURCE LINES 53-61

Setting Keyframes
=================

There are multiple ways to set keyframes:

1- To set a single keyframe, you may use ``animation.set_<property>(t, k)``,
where <property> is the name of the property to be set. I.e. setting position
to (1, 2, 3) at time 0.0 would be as following:

.. GENERATED FROM PYTHON SOURCE LINES 61-63

.. code-block:: Python

    anim.set_position(0.0, np.array([1, 2, 3]))








.. GENERATED FROM PYTHON SOURCE LINES 64-68

Supported properties are: **position, rotation, scale, color, and opacity**.

2- To set multiple keyframes at once, you may use
``animation.set_<property>_keyframes(keyframes)``.

.. GENERATED FROM PYTHON SOURCE LINES 68-72

.. code-block:: Python

    keyframes = {1.0: np.array([0, 0, 0]), 3.0: np.array([-2, 0, 0])}

    anim.set_position_keyframes(keyframes)








.. GENERATED FROM PYTHON SOURCE LINES 73-74

That's it! Now we are done setting keyframes.

.. GENERATED FROM PYTHON SOURCE LINES 76-78

In order to control this animation by the timeline we created earlier, this
animation must be added to the timeline.

.. GENERATED FROM PYTHON SOURCE LINES 78-80

.. code-block:: Python

    timeline.add_animation(anim)








.. GENERATED FROM PYTHON SOURCE LINES 81-83

Now we add only the ``Timeline`` to the ``ShowManager`` the same way we add
``Animation`` to the ``ShowManager``.

.. GENERATED FROM PYTHON SOURCE LINES 83-93

.. code-block:: Python

    showm.add_animation(timeline)

    scene.set_camera(position=(0, 0, -10))

    interactive = False

    if interactive:
        showm.start()

    window.record(scene, out_path='viz_keyframe_animation_timeline.png', size=(900, 768))
