ManimMob¶

Qualified name: algan.mobs.manim\_mob.ManimMob

class ManimMob(manim_mob, batch=False, _add_to_scene=None, **kwargs)[source]¶

Bases: BezierCircuitCubic

Constructs an equivalent Algan Mob from a given Manim Mobject.

Manim’s 3-D Mobjects convert too, and arrive as real 3-D geometry rather than flattened onto a plane. A Surface – and everything built on it, Sphere, Torus, Cone – is a grid of curved quad tiles in Manim, and each tile becomes one of the curved patches Algan’s own 3-D shapes are made of; a 3-D path such as a helical ParametricFunction keeps its position in space while its stroke keeps a constant width on screen. Both are ordinary geometry, so shadows, reflections and materials apply to them. See Bezier outlines that are not flat for what that costs.

Note that Manim’s z axis points opposite to Algan’s, so a converted Sphere has its poles facing the camera until you rotate it.

Parameters:

manim_mob (manim.Mobject) – The Manim Mobject which will be converted into an Algan Mob. It must be a bezier-circuit based object.
batch – Whether to pack the converted sub-hierarchy into one batched Mob, which renders far faster for a Mobject made of many similar parts (a Surface’s tiles, a page of Text). Defaults to False: a batch adopts the classification its FIRST member derived from geometry, so a group mixing kinds – a Sphere and a flat Square in one VGroup – currently loses the members that disagree with it.
**kwargs – Passed to BezierCircuitCubic .

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).
