Cone

Qualified name: manim.mobject.three\_dimensions.Cone

class Cone(base_radius=1, height=1, direction=array([0., 0., 1.]), show_base=False, v_range=[0, 6.283185307179586], u_min=0, checkerboard_colors=False, **kwargs)[source]

Bases: manim.mobject.three_dimensions.Surface

A circular cone. Can be defined using 2 parameters: its height, and its base radius. The polar angle, theta, can be calculated using arctan(base_radius / height) The spherical radius, r, is calculated using the pythagorean theorem.

Examples

Example: ExampleCone

../_images/ExampleCone-1.png
from manim import *

class ExampleCone(ThreeDScene):
    def construct(self):
        axes = ThreeDAxes()
        cone = Cone(direction=X_AXIS+Y_AXIS+2*Z_AXIS)
        self.set_camera_orientation(phi=5*PI/11, theta=PI/9)
        self.add(axes, cone)
Parameters
  • base_radius (float) – The base radius from which the cone tapers.

  • height (float) – The height measured from the plane formed by the base_radius to the apex of the cone.

  • direction (numpy.array) – The direction of the apex.

  • show_base (bool) – Whether to show the base plane or not.

  • v_range (Sequence[float]) – The azimuthal angle to start and end at.

  • u_min (float) – The radius at the apex.

  • checkerboard_colors (bool) – Show checkerboard grid texture on the cone.

Methods

func

Converts from spherical coordinates to cartesian.

get_direction

Uses shoelace_direction() to calculate the direction.

set_direction

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.

func(u, v)[source]

Converts from spherical coordinates to cartesian. :param u: The radius. :type u: float :param v: The azimuthal angle. :type v: float

get_direction()[source]

Uses shoelace_direction() to calculate the direction. The direction of points determines in which direction the object is drawn, clockwise or counterclockwise.

Examples

The default direction of a Circle is counterclockwise:

>>> from manim import Circle
>>> Circle().get_direction()
'CCW'
Returns

Either "CW" or "CCW".
