Camera

Balík: @aspose/3d (v24.12.0)

Camera je Entity ktorý môže byť pripojený k Node na definovanie pohľadu v scéne. Podporuje perspektívne aj ortografické projekcie, ktoré riadi projectionType vlastnosť. Parametre kamery sa ukladajú do 3D súboru, keď sa scéna uloží do formátu, ktorý podporuje kamery (FBX, COLLADA, glTF).

export class Camera extends Entity

Pridajte perspektívnu kameru do scény a nakonfigurujte jej frustum.

import { Scene, Node, Camera, ProjectionType } from '@aspose/3d';

const scene = new Scene();

const camNode = scene.rootNode.createChildNode('mainCamera');
const camera = new Camera('mainCamera', ProjectionType.PERSPECTIVE);
camNode.entity = camera;

camera.nearPlane = 0.1;
camera.farPlane = 500;
camera.fieldOfView = 60;
camera.aspect = 16 / 9;

scene.save('output.gltf');
console.log(`Camera projection: ${camera.projectionType}`);
// Camera projection: PERSPECTIVE

moveForward(distance)

Posúva kameru dopredu pozdĺž jej smeru pohľadu o zadanú vzdialenosť.

moveForward(distance: number): void

distance number

Vzdialenosť, o ktorú sa má posunúť dopredu. Záporné hodnoty posúvajú kameru dozadu.

V zdrojovom kóde, Camera dedí od Entity. Light tiež rozširuje Camera, čo znamená Light objekty majú všetky vlastnosti kamier v hierarchii typov; to odráža dátový model FBX, kde svetlá a kamery zdieľajú spoločný základný typ uzla.
Použite ProjectionType konštanty triedy (ProjectionType.PERSPECTIVE, ProjectionType.ORTHOGRAPHIC) namiesto surových reťazcových literálov pre typovú bezpečnosť.
