RegularPolygon

Qualified name: algan.mobs.shapes\_2d.RegularPolygon

class RegularPolygon(n=6, *, radius=1, start_angle=None, **kwargs)

Bases: Polygon

A regular polygon: n equal sides on a circle.

Parameters:

• n (int) – Number of sides. Defaults to 6; must be at least 3.

• radius (float) – Distance from the center to each vertex, in world units. Defaults to 1.

• start_angle (float | None) – Angle of the first vertex, in radians (Manim’s convention). Defaults to None, which puts the first vertex at the top and repeats the closing vertex – a topology that matters when morphing with become().

• **kwargs – Passed to Polygon and on to BezierCircuitCubic.

Raises:

ValueError – If fewer than 3 sides are requested.

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).
