Line¶

Qualified name: manim.mobject.geometry.Line

class Line(start=array([- 1., 0., 0.]), end=array([1., 0., 0.]), buff=0, path_arc=None, **kwargs)[source]¶

Bases: manim.mobject.geometry.TipableVMobject

Methods

`account_for_buff`
`generate_points`	Initializes `points` and therefore the shape.
`get_angle`
`get_projection`	Returns the projection of a point onto a line.
`get_slope`
`get_unit_vector`
`get_vector`
`init_points`	Initializes `points` and therefore the shape.
`pointify`
`put_start_and_end_on`	Sets starts and end coordinates of a line.
`set_angle`
`set_length`
`set_opacity`
`set_path_arc`
`set_points_by_ends`
`set_start_and_end_attrs`

Attributes

`animate`	Used to animate the application of a method.
`animation_overrides`
`depth`	The depth of the mobject.
`height`	The height of the mobject.
`width`	The width of the mobject.

generate_points()[source]¶

Initializes points and therefore the shape.

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

get_projection(point)[source]¶

Returns the projection of a point onto a line.

Parameters: point (Sequence[float]) – The point to which the line is projected.
Return type: Sequence[float]

init_points()¶

Initializes points and therefore the shape.

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

put_start_and_end_on(start, end)[source]¶

Sets starts and end coordinates of a line. .. rubric:: Examples

Example: LineExample ¶

from manim import *

class LineExample(Scene):
    def construct(self):
        d = VGroup()
        for i in range(0,10):
            d.add(Dot())
        d.arrange_in_grid(buff=1)
        self.add(d)
        l= Line(d[0], d[1])
        self.add(l)
        self.wait()
        l.put_start_and_end_on(d[1].get_center(), d[2].get_center())
        self.wait()
        l.put_start_and_end_on(d[4].get_center(), d[7].get_center())
        self.wait()

Parameters

start (Sequence[float]) –
end (Sequence[float]) –
