Icosahedron

Qualified name: algan.mobs.shapes\_3d.Icosahedron

class Icosahedron(edge_length=1, **kwargs)

Bases: Polyhedron

The twenty-faced Platonic solid, built from flat triangular faces.

Parameters:

• edge_length – Length of every edge, in world units. Defaults to 1.

• **kwargs – Passed to Polyhedron – notably color and location.

Examples

Example: Example1Icosahedron

from algan import *

Icosahedron(edge_length=0.8, color=BLUE).spawn()

Scene.save_video()

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	get_render_primitives below hands the renderer every face under one _mesh_key, and nothing else -- so the faces are this Mob's internals rather than Mobs of their own, and the vertex Dot3D``s and edge Mobs under ``self.graph (kept for Manim parity, where graph_config styles them) are geometry it owns but never puts on screen.
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).
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).
