Creating hierarchical keyframes animation in fury

.. GENERATED FROM PYTHON SOURCE LINES 8-21

.. code-block:: Python

    scene = window.Scene()

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

Creating the road

Constructing the car geometry

    body_actor = actor.box(

        colors=(0.6, 0.3, 0.1),
    )

Adding the the car's body to an Animation to be able to animate it later.

.. GENERATED FROM PYTHON SOURCE LINES 38-40

.. code-block:: Python

    car_anim = Animation(body_actor)


.. GENERATED FROM PYTHON SOURCE LINES 41-42

Creating the wheels of the car

.. GENERATED FROM PYTHON SOURCE LINES 42-65

.. code-block:: Python

    wheel_center = np.array([[0, 0, 0]])

    wheel_direction = np.array([[0, 0, 1]])
    wheel_positions = [
        [1.2, 0, 1.1],
        [-1.2, 0, 1.1],
        [1.2, 0, -1.1],
        [-1.2, 0, -1.1],
    ]

    wheels = [
        actor.cylinder(
            wheel_center,
            wheel_direction,

            capped=True,
        )
        for _ in range(4)

.. GENERATED FROM PYTHON SOURCE LINES 66-68

Animating each wheel and setting its position to the right position using a
single keyframe that will not change.

.. GENERATED FROM PYTHON SOURCE LINES 68-76

.. code-block:: Python


    wheels_animations = [Animation(wheel) for wheel in wheels]

    for wheel_anim in wheels_animations:
        wheel_anim.set_position(0.0, wheel_positions.pop())
        wheel_anim.set_rotation(0.0, [0, 0, 1, 1])
        wheel_anim.set_rotation(1.0, [0, 0, 1, -1])


.. GENERATED FROM PYTHON SOURCE LINES 77-78

Creating a radar on top of the car

.. GENERATED FROM PYTHON SOURCE LINES 80-81

First we create the shaft holding and rotating the radar

.. GENERATED FROM PYTHON SOURCE LINES 81-85

.. code-block:: Python

    radar_shaft = actor.cylinder(
        np.array([[0, 0, 0]]), np.array([[0, 1, 0]]), (0, 1, 0), heights=1
    )


.. GENERATED FROM PYTHON SOURCE LINES 86-87

In order to animate the shaft actor we have to add it to an Animation

.. GENERATED FROM PYTHON SOURCE LINES 87-89

.. code-block:: Python

    radar_shaft_anim = Animation(radar_shaft)


.. GENERATED FROM PYTHON SOURCE LINES 90-92

Setting a single position keyframe will make sure the actor will be placed at
that position

.. GENERATED FROM PYTHON SOURCE LINES 92-94

.. code-block:: Python

    radar_shaft_anim.set_position(0.0, [0, 2, 0])


.. GENERATED FROM PYTHON SOURCE LINES 95-96

Rotating the shaft around Y axis

.. GENERATED FROM PYTHON SOURCE LINES 96-100

.. code-block:: Python

    radar_shaft_anim.set_rotation(0.0, [0, -250, 0])
    radar_shaft_anim.set_rotation(1.0, [0, 250, 0])
    radar_shaft_anim.set_rotation(2.0, [0, -250, 0])


.. GENERATED FROM PYTHON SOURCE LINES 101-102

Now we create the radar itself

.. GENERATED FROM PYTHON SOURCE LINES 102-104

.. code-block:: Python

    radar = actor.cone(np.array([[0, 0, 0]]), directions=(0, 0, 0), colors=(0.2, 0.2, 0.9))


.. GENERATED FROM PYTHON SOURCE LINES 105-106

Then add it to an animation in order to rotate it

.. GENERATED FROM PYTHON SOURCE LINES 106-108

.. code-block:: Python

    radar_animation = Animation(radar)


.. GENERATED FROM PYTHON SOURCE LINES 109-110

Set position and rotation as done above with the shaft.

.. GENERATED FROM PYTHON SOURCE LINES 110-115

.. code-block:: Python

    radar_animation.set_position(0, [-0.4, 0.5, 0])
    radar_animation.set_rotation(0.0, [0, 0, 0])
    radar_animation.set_rotation(1.0, [180, 0, 0])
    radar_animation.set_rotation(2.0, [0, 0, 0])


.. GENERATED FROM PYTHON SOURCE LINES 116-119

Now, we want the radar to rotate when the shaft rotates in hierarchical way.
To do that we must add the radar animation as a child animation of the shaft
animation as below:

.. GENERATED FROM PYTHON SOURCE LINES 119-121

.. code-block:: Python

    radar_shaft_anim.add_child_animation(radar_animation)


.. GENERATED FROM PYTHON SOURCE LINES 122-125

After that we want everything to animate related to the car.
The wheels should always be attached to the car no matter where it moves.
we do that by adding them as child animations of the car's body animation

.. GENERATED FROM PYTHON SOURCE LINES 125-127

.. code-block:: Python

    car_anim.add_child_animation([wheels_animations, radar_shaft_anim])


.. GENERATED FROM PYTHON SOURCE LINES 128-129

Moving the car

.. GENERATED FROM PYTHON SOURCE LINES 129-132

.. code-block:: Python

    car_anim.set_position(0.0, [-10, 0.5, 0])
    car_anim.set_position(6.0, [10, 0.5, 0])


.. GENERATED FROM PYTHON SOURCE LINES 133-134

Adding the car Animation to the show manager

.. GENERATED FROM PYTHON SOURCE LINES 134-146

.. code-block:: Python

    showm.add_animation(car_anim)
    scene.add(road)
    scene.camera().SetPosition(0, 20, 30)

    interactive = False

    if interactive:
        showm.start()

    window.record(
        scene, out_path="viz_keyframe_hierarchical_animation.png", size=(900, 768)
    )
