Polygram#

Qualified name: manim.mobject.geometry.polygram.Polygram

class Polygram(*vertex_groups, color='#58C4DD', **kwargs)[source]#

Bases: VMobject

A generalized Polygon, allowing for disconnected sets of edges.

Parameters

vertex_groups (Iterable[Sequence[float]]) –
The groups of vertices making up the Polygram.

The first vertex in each group is repeated to close the shape. Each point must be 3-dimensional: [x,y,z]
color – The color of the Polygram.
kwargs – Forwarded to the parent constructor.

Examples

Example: PolygramExample ¶

from manim import *

import numpy as np

class PolygramExample(Scene):
    def construct(self):
        hexagram = Polygram(
            [[0, 2, 0], [-np.sqrt(3), -1, 0], [np.sqrt(3), -1, 0]],
            [[-np.sqrt(3), 1, 0], [0, -2, 0], [np.sqrt(3), 1, 0]],
        )
        self.add(hexagram)

        dot = Dot()
        self.play(MoveAlongPath(dot, hexagram), run_time=5, rate_func=linear)
        self.remove(dot)
        self.wait()

Methods

`get_vertex_groups`	Gets the vertex groups of the `Polygram`.
`get_vertices`	Gets the vertices of the `Polygram`.
`round_corners`	Rounds off the corners of the `Polygram`.

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.

get_vertex_groups()[source]#

Gets the vertex groups of the Polygram.

Returns: The vertex groups of the Polygram.
Return type: numpy.ndarray

Examples

>>> poly = Polygram([ORIGIN, RIGHT, UP], [LEFT, LEFT + UP, 2 * LEFT])
>>> poly.get_vertex_groups()
array([[[ 0.,  0.,  0.],
        [ 1.,  0.,  0.],
        [ 0.,  1.,  0.]],

       [[-1.,  0.,  0.],
        [-1.,  1.,  0.],
        [-2.,  0.,  0.]]])

get_vertices()[source]#

Gets the vertices of the Polygram.

Returns: The vertices of the Polygram.
Return type: numpy.ndarray

Examples

>>> sq = Square()
>>> sq.get_vertices()
array([[ 1.,  1.,  0.],
       [-1.,  1.,  0.],
       [-1., -1.,  0.],
       [ 1., -1.,  0.]])

round_corners(radius=0.5)[source]#

Rounds off the corners of the Polygram.

Parameters: radius (float) – The curvature of the corners of the Polygram.
