Class: ZoomDisplayPopOut

Defined in: core/ZoomedScene.ts:170

Animation that pops the zoomed display out from the camera frame to its target position, mimicking Manim's get_zoomed_display_pop_out_animation().

In begin(), the display's current position/scale are saved, then the display is snapped onto the camera frame via replace(frame, stretch=true). interpolate(alpha) lerps from frame-matched state (alpha=0) to the saved original state (alpha=1). Works with reversed rate functions for reverse pop-out.

protected _hasBegun: boolean = false

Defined in: animation/Animation.ts:38

Track if begin() has been called

Inherited from

---

_isFinished

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

---

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

---

rateFunc

readonly rateFunc: RateFunction

Defined in: animation/Animation.ts:29

---

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

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: core/ZoomedScene.ts:182

Called when the animation starts. Subclasses can override to set up initial state. On the very first call, captures a snapshot of the mobject so that reset() can restore it for clean backward seeking.

Returns

void

Overrides

Animation.begin

---

finish()

finish(): void

Defined in: core/ZoomedScene.ts:215

Called when the animation ends. Subclasses can override to clean up or finalize state.

Returns

void

Overrides

Animation.finish

---

interpolate()

interpolate(alpha): void

Defined in: core/ZoomedScene.ts:198

Apply the animation at a given progress value.

Parameters

alpha

number

Progress from 0 (start) to 1 (end)

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
