ArcPolygon¶

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

class ArcPolygon(*vertices, angle=0.7853981633974483, radius=None, arc_config=None, **kwargs)¶

Bases: ManimCompatMob

A generalized polygon allowing for points to be connected with arcs.

This version tries to stick close to the way Polygon is used. Points can be passed to it directly which are used to generate the according arcs (using ArcBetweenPoints). An angle or radius can be passed to it to use across all arcs, but to configure arcs individually an arc_config list has to be passed with the syntax explained below.

Parameters:

vertices (Point3DLike) – A list of vertices, start and end points for the arc segments.
angle (float) – The angle used for constructing the arcs. If no other parameters are set, this angle is used to construct all arcs.
radius (float | None) – The circle radius used to construct the arcs. If specified, overrides the specified angle.
arc_config (list[dict] | None) – When passing a dict, its content will be passed as keyword arguments to ArcBetweenPoints. Otherwise, a list of dictionaries containing values that are passed as keyword arguments for every individual arc can be passed.
kwargs (Any) – Further keyword arguments that are passed to the constructor of VMobject.

arcs¶

The arcs created from the input parameters:

>>> from manim import ArcPolygon
>>> ap = ArcPolygon([0, 0, 0], [2, 0, 0], [0, 2, 0])
>>> ap.arcs
[ArcBetweenPoints, ArcBetweenPoints, ArcBetweenPoints]

Type:: list

Tip

Two instances of ArcPolygon can be transformed properly into one another as well. Be advised that any arc initialized with angle=0 will actually be a straight line, so if a straight section should seamlessly transform into an arced section or vice versa, initialize the straight section with a negligible angle instead (such as angle=0.0001).

Note

There is an alternative version (ArcPolygonFromArcs) that is instantiated with pre-defined arcs.

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).
