Class: CameraAnimateProxy

Defined in: core/CameraFrame.ts:375

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.

Whether the animation has finished

Inherited from

Animation._isFinished

---

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/CameraFrame.ts:449

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/CameraFrame.ts:489

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

Returns

void

Overrides

Animation.finish

---

getFrame()

getFrame(): CameraFrame

Defined in: core/CameraFrame.ts:495

Get the CameraFrame this proxy animates.

Returns

CameraFrame

---

incrementGamma()

incrementGamma(delta): this

Defined in: core/CameraFrame.ts:412

Animate incrementing gamma by delta.

Parameters

delta

number

Returns

this

---

incrementPhi()

incrementPhi(delta): this

Defined in: core/CameraFrame.ts:406

Animate incrementing phi by delta.

Parameters

delta

number

Returns

this

---

incrementTheta()

incrementTheta(delta): this

Defined in: core/CameraFrame.ts:400

Animate incrementing theta by delta.

Parameters

delta

number

Returns

this

---

interpolate()

interpolate(alpha): void

Defined in: core/CameraFrame.ts:458

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

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

---

moveTo()

moveTo(point): this

Defined in: core/CameraFrame.ts:430

Animate moving the look-at center.

Parameters

point

Vector3Tuple

Returns

this

---

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

---

setDistance()

Defined in: core/CameraFrame.ts:418

Animate setting distance.

Parameters

value

number

Returns

this

---

setEulerAngles()

setEulerAngles(opts): this

Defined in: core/CameraFrame.ts:392

Animate setting Euler angles (absolute targets).

Parameters

opts

gamma?

number

phi?

number

theta?

number

Returns

this

---

setFieldOfView()

setFieldOfView(fov): this

Defined in: core/CameraFrame.ts:424

Animate setting field of view.

Parameters

fov

number

Returns

this

---

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
