autk-map / Camera

Class: Camera

Defined in: camera.ts:8

Camera class for managing the view parameters and transformations in a 3D space. It provides methods to manipulate the camera position, orientation, and projection.

Constructors

Constructor

new Camera(params?): Camera

Defined in: camera.ts:81

Constructs a Camera instance with the specified parameters. If no parameters are provided, it uses the default camera parameters.

Parameters

params?

ICameraData = Camera.defaultParams

The initial camera parameters.

Returns

Camera

Defined in: camera.ts:112

Gets the projection matrix for the camera.

Returns

number[] | Float32Array<ArrayBufferLike>

The projection matrix

---

pitch()

pitch(delta): void

Defined in: camera.ts:189

Pitches the camera around the x-axis.

Parameters

delta

number

The amount to pitch the camera (in radians).

Returns

void
