Class: MappingCamera
Defined in: core/CameraExtensions.ts:1008
MappingCamera - A Camera2D that applies a coordinate mapping function to transform how the scene is viewed.
Based on Python Manim's MappingCamera concept. Use cases include non-linear coordinate distortions and custom projections.

Constructors
Constructor
new MappingCamera(
options):MappingCamera
Defined in: core/CameraExtensions.ts:1015
Create a new MappingCamera.
Parameters
options
MappingCameraOptions = {}
Camera configuration options
Returns
MappingCamera
Overrides
Accessors
aspectMode
Get Signature
get aspectMode():
Camera2DAspectMode
Defined in: core/Camera.ts:345
Get the current aspect-mode (see Camera2DAspectMode).
Returns
Set Signature
set aspectMode(
mode):void
Defined in: core/Camera.ts:353
Set the aspect-mode. Re-applies the current aspect ratio so the projection updates immediately.
Parameters
mode
Returns
void
Inherited from
frame
Get Signature
get frame():
Camera2DFrame
Defined in: core/Camera.ts:416
Lazy-created Camera2DFrame for Manim-style camera.frame API. The frame is a VMobject whose position and scale drive the camera, enabling animations like Restore, MoveToTarget, and updaters.
Returns
Inherited from
frameHeight
Get Signature
get frameHeight():
number
Defined in: core/Camera.ts:329
Get the frame height in world units.
Returns
number
Set Signature
set frameHeight(
height):void
Defined in: core/Camera.ts:336
Set the frame height in world units.
Parameters
height
number
Returns
void
Inherited from
frameWidth
Get Signature
get frameWidth():
number
Defined in: core/Camera.ts:313
Get the frame width in world units.
Returns
number
Set Signature
set frameWidth(
width):void
Defined in: core/Camera.ts:320
Set the frame width in world units.
Parameters
width
number
Returns
void
Inherited from
position
Get Signature
get position():
Vector3
Defined in: core/Camera.ts:363
Get the camera position.
Returns
Vector3

Methods
getCamera()
getCamera():
OrthographicCamera
Defined in: core/Camera.ts:380
Get the underlying Three.js OrthographicCamera.
Returns
OrthographicCamera
The OrthographicCamera instance
Inherited from
getMappingFunction()
getMappingFunction():
MappingFunction
Defined in: core/CameraExtensions.ts:1034
Get the current mapping function.
Returns
The mapping function, or null if none is set
mapPoint()
mapPoint(
point):Vector3Tuple
Defined in: core/CameraExtensions.ts:1044
Apply the mapping function to a point. Returns the point unchanged if no mapping is set (identity).
Parameters
point
Input point [x, y, z]
Returns
The mapped point
moveTo()
moveTo(
point):void
Defined in: core/Camera.ts:371
Move the camera to a specific point.
Parameters
point
[number, number, number]
Target position [x, y, z]
Returns
void
Inherited from
resetMapping()
resetMapping():
this
Defined in: core/CameraExtensions.ts:1055
Clear the mapping function, reverting to identity.
Returns
this
this for chaining
setAspectRatio()
setAspectRatio(
aspectRatio):void
Defined in: core/Camera.ts:389
Update the frame dimensions to match an aspect ratio. Useful for responsive layouts.
Parameters
aspectRatio
number
Width / height ratio
Returns
void
Inherited from
setMappingFunction()
setMappingFunction(
fn):this
Defined in: core/CameraExtensions.ts:1025
Set the mapping function used to transform coordinates.
Parameters
fn
Mapping function that transforms [x, y, z] points
Returns
this
this for chaining
updateFrame()
updateFrame(
dt):void
Defined in: core/Camera.ts:428
Run updaters on the camera frame (if it exists). Called by Scene after the timeline update so camera updaters see the latest positions set by animations.
Parameters
dt
number
Returns
void
