Rotating¶

Qualified name: manim.animation.rotation.Rotating

class Rotating(mobject=None, *args, use_override=True, **kwargs)[source]¶

Bases: Animation

Animation that rotates a Mobject.

Parameters:

mobject (Mobject) – The mobject to be rotated.
angle (float) – The rotation angle in radians. Predefined constants such as DEGREES can also be used to specify the angle in degrees.
axis (Vector3DLike) – The rotation axis as a numpy vector.
about_point (Point3DLike | None) – The rotation center.
about_edge (Vector3DLike | None) – If about_point is None, this argument specifies the direction of the bounding box point to be taken as the rotation center.
run_time (float) – The duration of the animation in seconds.
rate_func (Callable[[float], float]) – The function defining the animation progress based on the relative runtime (see rate_functions) .
**kwargs (Any) – Additional keyword arguments passed to Animation.

Example: RotatingDemo ¶

from manim import *

    def construct(self):
        circle = Circle(radius=1, color=BLUE)
        line = Line(start=ORIGIN, end=RIGHT)
        arrow = Arrow(start=ORIGIN, end=RIGHT, buff=0, color=GOLD)
        vg = VGroup(circle,line,arrow)
        self.add(vg)
        anim_kw = {"about_point": arrow.get_start(), "run_time": 1}
        self.play(Rotating(arrow, 180*DEGREES, **anim_kw))
