Cone

Qualified name: algan.mobs.manim\_compat.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)

Bases: ManimCompatMob

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.

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 (Vector3DLike) – The direction of the apex.

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

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

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

  • checkerboard_colors (Iterable[ParsableManimColor] | Literal[False]) – Show checkerboard grid texture on the cone.

  • kwargs (Any)

Methods

Attributes

animation_manager

This mob's scene-owned animation manager.

basis

The Mob's orientation and scale, as a flattened 3x3 matrix of shape (*, 9).

casts_shadows

Whether this Mob's geometry blocks light on its way from a light source to another surface -- whether it casts a shadow.

children

The Mobs attached below this one, in attachment order.

closed_shell

Whether this Mob's triangles form a CLOSED shell -- every camera ray that enters the geometry crosses a second time on its way out.

draws_descendants

Whether get_render_primitives returns geometry belonging to this Mob's DESCENDANTS as well as its own.

forward

Get the direction the Mob is facing.

lifespan

This mob's [spawn, despawn) interval on its Scene timeline (a Lifespan).

location

The Mob's position in world space, shape (*, 3).

normalized_basis

The Mob's orientation with scale divided out, shape (*, 9).

parents

The Mobs this one is attached to, in attachment order.

receives_shadows

Whether this Mob's surfaces are darkened by shadows cast onto them.

right

Get the Mob's own rightward direction.

scale_coefficient

The Mob's scale along its own right, up and forward axes, shape (*, 3).

stroke_color

The color of the circuit's border stroke.

two_sided

Whether this Mob's geometry should be lit from whichever side the ray arrives on.

up

Get the Mob's own upward direction.

x

The Mob's x coordinate in world units, shape (*, 1).

xy

The Mob's x and y coordinates in world units, shape (*, 2).

y

The Mob's y coordinate in world units, shape (*, 1).

z

The Mob's z coordinate in world units, shape (*, 1).

z_index

Which of two exactly coplanar circuits draws in front (higher wins).
