Annulus¶

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

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

Bases: Circle

Region between two concentric Circles.

Parameters:

inner_radius (float) – The radius of the inner Circle.
outer_radius (float) – The radius of the outer Circle.
kwargs (Any) – Additional arguments to be passed to Annulus
fill_opacity (float)
stroke_width (float)
color (ParsableManimColor)
mark_paths_closed (bool)

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)

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`

Attributes

`always`	Call a method on a mobject every frame.
`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.

_original__init__(inner_radius=1, outer_radius=2, fill_opacity=1, stroke_width=0, color=ManimColor('#FFFFFF'), mark_paths_closed=False, **kwargs)¶

Initialize self. See help(type(self)) for accurate signature.

Parameters:

inner_radius (float)
outer_radius (float)
fill_opacity (float)
stroke_width (float)
color (ParsableManimColor)
mark_paths_closed (bool)
kwargs (Any)

Return type:

None

generate_points()[source]¶

Initializes points and therefore the shape.

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

Return type:: None
