Arc

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

class Arc(radius=1.0, start_angle=0, angle=1.5707963267948966, num_components=9, arc_center=array([0., 0., 0.]), **kwargs)

Bases: TipableVMobject

A circular arc.

Examples

A simple arc of angle Pi.

Example: ArcExample

from manim import *

class ArcExample(Scene):
    def construct(self):
        self.add(Arc(angle=PI))

class ArcExample(Scene):
    def construct(self):
        self.add(Arc(angle=PI))

Methods

generate_points	Initializes points and therefore the shape.
get_arc_center	Looks at the normals to the first two anchors, and finds their intersection points
init_points
move_arc_center_to
stop_angle

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.

Parameters:

• radius (float | None)

• start_angle (float)

• angle (float)

• num_components (int)

• arc_center (Point3DLike)

• kwargs (Any)

_original__init__(radius=1.0, start_angle=0, angle=1.5707963267948966, num_components=9, arc_center=array([0., 0., 0.]), **kwargs)

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

Parameters:

• radius (float | None)

• start_angle (float)

• angle (float)

• num_components (int)

• arc_center (Point3DLike)

• kwargs (Any)

generate_points()

Initializes points and therefore the shape.

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

Return type:

None

get_arc_center(warning=True)

Looks at the normals to the first two anchors, and finds their intersection points

Parameters:

warning (bool)

Return type:

Point3D
