Cylinder#

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

class Cylinder(radius=1, height=2, direction=array([0., 0., 1.]), v_range=[0, 6.283185307179586], show_ends=True, resolution=(24, 24), **kwargs)[source]#

Bases: Surface

A cylinder, defined by its height, radius and direction,

Parameters:

radius (float) – The radius of the cylinder.
height (float) – The height of the cylinder.
direction (np.ndarray) – The direction of the central axis of the cylinder.
v_range (Sequence[float]) – The height along the height axis (given by direction) to start and end on.
show_ends (bool) – Whether to show the end caps or not.
resolution (Sequence[int]) – The number of samples taken of the Cylinder. A tuple can be used to define different resolutions for u and v respectively.

Examples

Example: ExampleCylinder ¶

from manim import *

class ExampleCylinder(ThreeDScene):
    def construct(self):
        axes = ThreeDAxes()
        cylinder = Cylinder(radius=2, height=3)
        self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES)
        self.add(axes, cylinder)

class ExampleCylinder(ThreeDScene):
    def construct(self):
        axes = ThreeDAxes()
        cylinder = Cylinder(radius=2, height=3)
        self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES)
        self.add(axes, cylinder)

Methods
