============================
Morphing Animation in a glTF
============================
In this tutorial, we will show how to use morphing in a glTF model in FURY.

.. GENERATED FROM PYTHON SOURCE LINES 7-10

.. code-block:: Python


    import fury








.. GENERATED FROM PYTHON SOURCE LINES 11-13

Retrieving the model with morphing in it (look at Khronoos samples).
We're choosing the `MorphStressTest` model here.

.. GENERATED FROM PYTHON SOURCE LINES 13-17

.. code-block:: Python


    fury.data.fetch_gltf("MorphStressTest", "glTF")
    filename = fury.data.read_viz_gltf("MorphStressTest")

    /opt/homebrew/Caskroom/miniforge/base/envs/py39/lib/python3.9/site-packages/sphinx_gallery/gen_rst.py:722: UserWarning: We'll no longer accept the way you call the fetch_gltf function in future versions of FURY.

    Here's how to call the Function fetch_gltf: fetch_gltf(name='value', mode='value')

      exec(self.code, self.fake_main.__dict__)




.. GENERATED FROM PYTHON SOURCE LINES 18-20

Initializing the glTF object, You can additionally set `apply_normals=True`.
Note: Normals might not work as intended with morphing.

.. GENERATED FROM PYTHON SOURCE LINES 20-23

.. code-block:: Python


    gltf_obj = fury.gltf.glTF(filename, apply_normals=True)








.. GENERATED FROM PYTHON SOURCE LINES 24-27

Get the morph timeline using `morph_timeline` method, Choose the animation
name you want to visualize.
Note: If there's no name for animation, It's stored as `anim_0`, `anim_1` etc

.. GENERATED FROM PYTHON SOURCE LINES 27-30

.. code-block:: Python


    animation = gltf_obj.morph_animation()["TheWave"]








.. GENERATED FROM PYTHON SOURCE LINES 31-33

Call the `update_morph` method once, This moves initialise the morphing at
timestamp 0.0 seconds and ensures that camera fits all the actors perfectly.

.. GENERATED FROM PYTHON SOURCE LINES 33-36

.. code-block:: Python


    gltf_obj.update_morph(animation)








.. GENERATED FROM PYTHON SOURCE LINES 37-40

Create a scene, and show manager.
Initialize the show manager and add timeline to the scene (No need to add
actors to the scene separately).

.. GENERATED FROM PYTHON SOURCE LINES 40-49

.. code-block:: Python


    scene = fury.window.Scene()
    showm = fury.window.ShowManager(
        scene, size=(900, 768), reset_camera=True, order_transparent=True
    )

    showm.initialize()
    scene.add(animation)

define a timer_callback.
Use the `update_morph` method again, It updates the timeline and applies
morphing).

    def timer_callback(_obj, _event):
        gltf_obj.update_morph(animation)
        showm.render()









.. GENERATED FROM PYTHON SOURCE LINES 61-62

Optional: `timeline.play()` auto plays the animations.

.. GENERATED FROM PYTHON SOURCE LINES 62-73

    showm.add_timer_callback(True, 20, timer_callback)
    scene.reset_camera()
