Arrow3D¶

Qualified name: manim.mobject.three\_d.three\_dimensions.Arrow3D

class Arrow3D(start=array([-1., 0., 0.]), end=array([1., 0., 0.]), thickness=0.02, height=0.3, base_radius=0.08, color=ManimColor('#FFFFFF'), resolution=24, **kwargs)[source]¶

Bases: Line3D

An arrow made out of a cylindrical line and a conical tip.

Parameters:

start (Point3DLike) – The start position of the arrow.
end (Point3DLike) – The end position of the arrow.
thickness (float) – The thickness of the arrow.
height (float) – The height of the conical tip.
base_radius (float) – The base radius of the conical tip.
color (ManimColor) – The color of the arrow.
resolution (int | tuple[int, int]) – The resolution of the arrow line.
kwargs (Any)

Examples

Example: ExampleArrow3D ¶

from manim import *

class ExampleArrow3D(ThreeDScene):
    def construct(self):
        axes = ThreeDAxes()
        arrow = Arrow3D(
            start=np.array([0, 0, 0]),
            end=np.array([2, 2, 2]),
            resolution=8
        )
        self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES)
        self.add(axes, arrow)

class ExampleArrow3D(ThreeDScene):
    def construct(self):
        axes = ThreeDAxes()
        arrow = Arrow3D(
            start=np.array([0, 0, 0]),
            end=np.array([2, 2, 2]),
            resolution=8
        )
        self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES)
        self.add(axes, arrow)

Methods
