Module anim 

Animations (SPEC §4.4): planned once at bake time, then sampled as a pure function of progress.

Structs

LaggedStart

Runs animations together, each starting lag_ratio of the previous one’s duration after it, manim’s LaggedStart. Like Parallel, all plan against the same start state.

Overlay

Helper shapes added to the scene now, invisible, animated by f from their added state, and removed when the clip ends: e.g. circumscribe and flash.

Parallel

Runs animations together; lasts as long as the longest. Each child keeps its own easing. Children targeting the same mobject: the last one wins.

ReplacementTransform

Morphs one mobject into another already in the scene, then swaps them, manim’s ReplacementTransform: target is hidden until the end, when it takes over and id is removed. See replacement_transform.

Sequence

Plays animations one after another, manim’s Succession; each plans against the scene as the previous one left it.

Timed

An animation with overridden timing; see AnimationExt.

Transform

Morphs a mobject into target (path, style and all).

Unwrite

Erases mobjects last to first, manim’s Unwrite: [write] played backwards. The mobjects stay in the scene until removed.

Update

Rewrites one mobject from its start-of-clip state and progress: the building block for the simple animations below.

UpdateGroup

Rewrites several mobjects together from each one’s start state, their joint bounding-box center and progress: the building block for the emphasis animations below.

Write

Draws mobjects in one after another, manim’s Write: each outline traces in, then its fill fades up while the outline fades back to its own style. See [write].

Enums

Ease

Curve shape for RateFn::EaseIn and friends.

RateFn

Maps linear progress 0..=1 to eased progress.

Traits

Animation

Something that changes the scene over a clip.

AnimationExt

Builder methods available on every animation.

Functions

apply_function

Morphs every control point q towards f(q), manim’s ApplyFunction / ApplyPointwise.

circumscribe

Draws a yellow rectangle around ids and erases it again, manim’s Circumscribe.

create

Draws the outline in along its arc length.

draw_border_then_fill

Traces the outline in, then fills it, manim’s DrawBorderThenFill; lasts 2 s. Like one mobject of [write].

fade_in

Fades from transparent to the current opacity.

fade_out

Fades to transparent. The mobject stays in the scene until removed.

flash

Twelve short yellow rays burst outwards from p, manim’s Flash.

grow_from_center

Grows from a point at its center, manim’s GrowFromCenter.

indicate

Briefly scales up by 1.2 and tints yellow, then settles back, manim’s Indicate.

lagged_start

Staggers anims by lag_ratio (0 is Parallel, 1 is back to back).

move_to

Moves so the bounding-box center ends at p.

replacement_transform

Morphs mobject id into mobject target (e.g. just added), leaving only target.

rotate

Rotates counter-clockwise by angle radians about the start bounding-box center.

scale

Scales by factor about the start bounding-box center.

shift

Translates by v.

shrink_to_center

Shrinks to a point at its center. The mobject stays in the scene until removed.

spin_in

Grows from a point while turning a quarter turn into place, manim’s SpinInFromNothing.

transform

Morphs mobject id into target.

uncreate

Erases the outline backwards along its arc length; the reverse of create. The mobject stays in the scene until removed.

unwrite

Unwrites ids (e.g. the glyphs of a text); the reverse of [write].

wiggle

Wobbles in place while swelling slightly, manim’s Wiggle; lasts 2 s.

write

Writes ids in order (e.g. the glyphs of a text), staggered like manim’s Write.
