Annulus

Qualified name: manim.mobject.geometry.arc.Annulus

class Annulus(inner_radius=1, outer_radius=2, fill_opacity=1, stroke_width=0, color='#FFFFFF', mark_paths_closed=False, **kwargs)

Bases: Circle

Region between two concentric Circles.

Parameters

• inner_radius (float | None) – The radius of the inner Circle.

• outer_radius (float | None) – The radius of the outer Circle.

• kwargs – Additional arguments to be passed to Annulus

Examples

Example: AnnulusExample

from manim import *

class AnnulusExample(Scene):
    def construct(self):
        annulus_1 = Annulus(inner_radius=0.5, outer_radius=1).shift(UP)
        annulus_2 = Annulus(inner_radius=0.3, outer_radius=0.6, color=RED).next_to(annulus_1, DOWN)
        self.add(annulus_1, annulus_2)

Methods

generate_points	Initializes points and therefore the shape.
init_points	Initializes points and therefore the shape.

Attributes

animate	Used to animate the application of any method of self.
animation_overrides
color
depth	The depth of the mobject.
fill_color	If there are multiple colors (for gradient) this returns the first one
height	The height of the mobject.
n_points_per_curve
sheen_factor
stroke_color
width	The width of the mobject.

generate_points()

Initializes points and therefore the shape.

Gets called upon creation. This is an empty method that can be implemented by subclasses.

init_points()

Initializes points and therefore the shape.

Gets called upon creation. This is an empty method that can be implemented by subclasses.
