Class: ComplexHomotopy

Defined in: animation/movement/Homotopy.ts:145

Homotopy in the complex plane where points are treated as complex numbers. The function operates on z = x + iy and returns a new complex number.

protected _isFinished: boolean = false

Defined in: animation/Animation.ts:35

Whether the animation has finished

Inherited from

Animation._isFinished

---

_startTime

protected _startTime: number = null

Defined in: animation/Animation.ts:32

Time when the animation started (set by Timeline)

Inherited from

Animation._startTime

---

complexFunc

readonly complexFunc: ComplexHomotopyFunction

Defined in: animation/movement/Homotopy.ts:147

The complex homotopy function

---

duration

readonly duration: number

Defined in: animation/Animation.ts:26

Duration of the animation in seconds

Inherited from

Animation.duration

---

mobject

readonly mobject: Mobject

Defined in: animation/Animation.ts:23

The mobject being animated

Inherited from

Animation.mobject

---

Defined in: animation/Animation.ts:29

Rate function controlling the animation's pacing

Inherited from

Animation.rateFunc

---

remover

remover: boolean = false

Defined in: animation/Animation.ts:44

If true, the scene will remove this mobject after the animation finishes. Used by FadeOut (like Python manim's remover=True).

Inherited from

Animation.remover

Accessors

startTime

Get Signature

get startTime(): number

Defined in: animation/Animation.ts:184

Get the start time of this animation (set by Timeline)

Returns

number

Set Signature

set startTime(time): void

Defined in: animation/Animation.ts:191

Set the start time of this animation (used by Timeline)

Parameters

time

number

Returns

void

Inherited from

Animation.startTime

Methods

begin()

begin(): void

Defined in: animation/movement/Homotopy.ts:163

Store the original points at animation start

Returns

void

Overrides

Animation.begin

---

finish()

finish(): void

Defined in: animation/movement/Homotopy.ts:205

Ensure the final state is exact

Returns

void

Overrides

Animation.finish

---

interpolate()

interpolate(alpha): void

Defined in: animation/movement/Homotopy.ts:178

Apply the complex homotopy at the given progress value

Parameters

alpha

number

Returns

void

Overrides

Animation.interpolate

---

isFinished()

isFinished(): boolean

Defined in: animation/Animation.ts:145

Check if the animation has finished

Returns

boolean

Inherited from

Animation.isFinished

---

reset()

reset(): void

Defined in: animation/Animation.ts:154

Reset the animation to its initial state. Restores the mobject to its pre-animation visual state so that re-seeking (especially backward) produces correct results.

Returns

void

Inherited from

Animation.reset

---

update()

update(_dt, currentTime): void

Defined in: animation/Animation.ts:122

Update the animation for the current frame.

Parameters

_dt

number

Time delta since last frame (unused, but available for subclasses)

currentTime

number

Current time in the timeline

Returns

void

Inherited from

Animation.update
