SpiralIn#

Qualified name: manim.animation.creation.SpiralIn

class SpiralIn(mobject=None, *args, use_override=True, **kwargs)[source]#

Bases: manim.animation.animation.Animation

Create the Mobject with sub-Mobjects flying in on spiral trajectories.

Parameters
  • shapes – The Mobject on which to be operated.

  • scale_factor – The factor used for scaling the effect.

  • fade_in_fraction – Fractional duration of initial fade-in of sub-Mobjects as they fly inward.

Examples

Example: SpiralInExample

from manim import *

class SpiralInExample(Scene):
    def construct(self):
        pi = MathTex(r"\pi").scale(7)
        pi.shift(2.25 * LEFT + 1.5 * UP)
        circle = Circle(color=GREEN_C, fill_opacity=1).shift(LEFT)
        square = Square(color=BLUE_D, fill_opacity=1).shift(UP)
        shapes = VGroup(pi, circle, square)
        self.play(SpiralIn(shapes))

Methods

interpolate_mobject

Interpolates the mobject of the Animation based on alpha value.

interpolate_mobject(alpha)[source]#

Interpolates the mobject of the Animation based on alpha value.

Parameters

alpha (float) – A float between 0 and 1 expressing the ratio to which the animation is completed. For example, alpha-values of 0, 0.5, and 1 correspond to the animation being completed 0%, 50%, and 100%, respectively.

Return type

None
