Class: CameraFrame

Defined in: core/CameraFrame.ts:44

CameraFrame wraps a Camera3D and exposes ManimGL-compatible Euler angle methods for both immediate use and animation (via the .animate proxy).

Constructors

Constructor

new CameraFrame(aspectRatio, options): CameraFrame

Defined in: core/CameraFrame.ts:60

Parameters

aspectRatio

number = ...

options

CameraFrameOptions = {}

Returns

CameraFrame

Properties

mobjectStub

readonly mobjectStub: Mobject

Defined in: core/CameraFrame.ts:58

A lightweight Mobject stub used as the Animation target. This lets CameraAnimation integrate with the existing Timeline / Scene.play() system which requires every Animation to have a .mobject.

Accessors

animate

Get Signature

get animate(): CameraAnimateProxy

Defined in: core/CameraFrame.ts:301

Returns a proxy that records camera state changes and produces a CameraAnimation when called with scene.play().

Usage (property, default 1s smooth): scene.play(frame.animate.incrementPhi(PI/4)) scene.play(frame.animate.setEulerAngles({ theta: PI/4, phi: PI/3 }))

Usage (method with options): scene.play(frame.animateTo({ duration: 2 }).incrementPhi(PI/4))

Returns

CameraAnimateProxy
