ArcBrace¶

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

class ArcBrace(arc=None, direction=array([1., 0., 0.]), **kwargs)¶

Bases: ManimCompatMob

Creates a Brace that wraps around an Arc.

The direction parameter allows the brace to be applied from outside or inside the arc.

Warning

The ArcBrace is smaller for arcs with smaller radii.

Note

The ArcBrace is initially a vertical Brace defined by the length of the Arc, but is scaled down to match the start and end angles. An exponential function is then applied after it is shifted based on the radius of the arc.

The scaling effect is not applied for arcs with radii smaller than 1 to prevent over-scaling.

Parameters:

arc (Arc | None) – The Arc that wraps around the Brace mobject.
direction (Vector3DLike) – The direction from which the brace faces the arc. LEFT for inside the arc, and RIGHT for the outside.
kwargs (Any)

Example

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).
