# SpiralIn#

Qualified name: manim.animation.creation.SpiralIn

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

Bases: Animation

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

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

• scale_factor (float) – 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
