Methods

getCamera()

getCamera(): PerspectiveCamera

Defined in: core/Camera.ts:55

Get the underlying Three.js PerspectiveCamera.

Returns

PerspectiveCamera

The PerspectiveCamera instance

---

getOrbitAngles()

getOrbitAngles(): object

Defined in: core/Camera.ts:155

Get spherical coordinates relative to the look-at point.

Returns

object

distance

distance: number

phi

phi: number

theta

theta: number

---

moveTo()

moveTo(position): this

Defined in: core/Camera.ts:85

Move the camera to a specific position.

Parameters

position

[number, number, number]

Target position [x, y, z]

Returns

this

this for chaining

---

orbit()

orbit(phi, theta, distance?): this

Defined in: core/Camera.ts:135

Orbit the camera around the look-at point using Python Manim convention. Manim rotation: R = Rx(-phi) @ Rz(-theta - PI/2), applied to scene points. Camera position in Manim space: (d*sin(phi)cos(theta), dsin(phi)sin(theta), dcos(phi))

Parameters

phi

number

Polar angle from Z axis (0 = top, PI/2 = side, PI = bottom)

theta

number

Azimuthal angle around Z axis

distance?

number

Optional distance from look-at point

Returns

this

this for chaining

---

setAspectRatio()

setAspectRatio(ratio): this

Defined in: core/Camera.ts:120

Update the aspect ratio.

Parameters

ratio

number

Width / height ratio

Returns

this

this for chaining

---

setFov()

setFov(fov): this

Defined in: core/Camera.ts:108

Set the field of view.

Parameters

fov

number

Field of view in degrees

Returns

this

this for chaining

---

setLookAt()

setLookAt(target): this

Defined in: core/Camera.ts:97

Set the look-at target.

Parameters

target

[number, number, number]

Target point [x, y, z]

Returns

this

this for chaining
