MultiPendulum

Qualified name: manim\_physics.rigid\_mechanics.pendulum.MultiPendulum

class MultiPendulum(*bobs, pivot_point=array([0., 2., 0.]), rod_style={}, bob_style={'color': ManimColor('#FF862F'), 'fill_opacity': 1, 'radius': 0.1}, **kwargs)

Bases: VGroup

A multipendulum.

Parameters:

• bobs (Iterable[np.ndarray]) – Positions of pendulum bobs.

• pivot_point (np.ndarray) – Position of the pivot.

• rod_style (dict) – Parameters for Line.

• bob_style (dict) – Parameters for Circle.

• kwargs – Additional parameters for VGroup.

Examples

Example: MultiPendulumExample

        self.make_rigid_body(*p.bobs)
        p.start_swinging()
        self.add(TracedPath(p.bobs[-1].get_center, stroke_color=BLUE))
        self.wait(10)
