Polyhedron¶

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

class Polyhedron(vertex_coords, faces_list, faces_config={}, graph_config={})¶

Bases: ManimCompatMob

An abstract polyhedra class.

In this implementation, polyhedra are defined with a list of vertex coordinates in space, and a list of faces. This implementation mirrors that of a standard polyhedral data format (OFF, object file format).

Parameters:

vertex_coords (Point3DLike_Array) – A list of coordinates of the corresponding vertices in the polyhedron. Each coordinate will correspond to a vertex. The vertices are indexed with the usual indexing of Python.
faces_list (list[list[int]]) – A list of faces. Each face is a sublist containing the indices of the vertices that form the corners of that face.
faces_config (dict[str, str | int | float | bool]) – Configuration for the polygons representing the faces of the polyhedron.
graph_config (dict[str, Any]) – Configuration for the graph containing the vertices and edges of the polyhedron.

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).
