Class: CameraAnimateProxy

Defined in: src/core/CameraFrame.ts:346

Fluent builder returned by CameraFrame.animate.

Each method records a target state change and returns this, so you can chain: frame.animate.incrementPhi(PI/4).setFieldOfView(60).

The proxy itself is used as the Animation argument to scene.play(). When play() calls .begin(), the proxy finalises the CameraAnimation.

Defined in: src/animation/Animation.ts:34

The mobject being animated

Inherited from

Animation.mobject

---

rateFunc

Animation.rateFunc

---

remover

remover: boolean = false

Defined in: src/animation/Animation.ts:55

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: src/animation/Animation.ts:236

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

Returns

number

Set Signature

set startTime(time): void

Defined in: src/animation/Animation.ts:243

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: src/core/CameraFrame.ts:420

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

---

cleanUpFromScene()

cleanUpFromScene(scene): void

Defined in: src/animation/Animation.ts:141

Hook called by Scene after the animation finishes, before the next play(). Default: removes mobject if remover is set (FadeOut, Write({remover:true})). Override for animations that need to mutate scene membership — e.g. ReplacementTransform swaps source for target.

Parameters

scene

AnimationScene

Returns

void

Inherited from

Animation.cleanUpFromScene

---

finish()

finish(): void

Defined in: src/core/CameraFrame.ts:460

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

Returns

void

Overrides

Animation.finish

---

getFrame()

getFrame(): CameraFrame

Defined in: src/core/CameraFrame.ts:466

Get the CameraFrame this proxy animates.

Returns

CameraFrame

---

getSubAlpha()

protected getSubAlpha(alpha, index, count, lagRatio): number

Defined in: src/animation/Animation.ts:161

Manim CE's get_sub_alpha: remaps a global progress alpha into the local progress of family member index (of count) under a lagRatio stagger. With lagRatio <= 0 (or a single member), every member tracks alpha directly. Subclasses that stagger across a mobject's family (e.g. Create) should index this by familyMembersWithPoints(), never by rendering-layer primitives.

Parameters

alpha

number

index

number

count

number

lagRatio

number

Returns

number

Inherited from

Animation.getSubAlpha

---

incrementGamma()

incrementGamma(delta): this

Defined in: src/core/CameraFrame.ts:383

Animate incrementing gamma by delta.

Parameters

delta

number

Returns

this

---

incrementPhi()

incrementPhi(delta): this

Defined in: src/core/CameraFrame.ts:377

Animate incrementing phi by delta.

Parameters

delta

number

Returns

this

---

incrementTheta()

incrementTheta(delta): this

Defined in: src/core/CameraFrame.ts:371

Animate incrementing theta by delta.

Parameters

delta

number

Returns

this

---

interpolate()

interpolate(alpha): void

Defined in: src/core/CameraFrame.ts:429

Interpolate camera state at the given alpha (0..1).

Parameters

alpha

number

Returns

void

Overrides

Animation.interpolate

---

isFinished()

isFinished(): boolean

Defined in: src/animation/Animation.ts:197

Check if the animation has finished

Returns

boolean

Inherited from

Animation.isFinished

---

moveTo()

moveTo(point): this

Defined in: src/core/CameraFrame.ts:401

Animate moving the look-at center.

Parameters

point

Vector3Tuple

Returns

this

---

reset()

reset(): void

Defined in: src/animation/Animation.ts:206

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

---

setDistance()

setDistance(value): this

Defined in: src/core/CameraFrame.ts:389

Animate setting distance.

Parameters

value

number

Returns

this

---

setEulerAngles()

Defined in: src/core/CameraFrame.ts:363

Animate setting Euler angles (absolute targets).

Parameters

opts

gamma?

number

phi?

number

theta?

number

Returns

this

---

setFieldOfView()

setFieldOfView(fov): this

Defined in: src/core/CameraFrame.ts:395

Animate setting field of view.

Parameters

---

withRateFunc()

withRateFunc(fn): this

Defined in: src/core/CameraFrame.ts:413

Override rate function (builder-style).
