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)

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_path_arc
set_points_by_ends
set_start_and_end_attrs

Attributes

animate	Used to animate the application of any method of self.
animation_overrides
depth	The depth of the mobject.
height	The height of the mobject.
width	The width of the mobject.

generate_points()

Initializes points and therefore the shape.

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

get_projection(point)

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)

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
