Camera

Paket: @aspose/3d (v24.12.0)

Camera je Entity koja se može priložiti Node za definiranje pogleda u sceni. Podržava i perspektivne i ortografske projekcije, kontrolirane putem projectionType svojstva. Parametri kamere pohranjuju se u 3D datoteku kada se scena spremi u format koji podržava kamere (FBX, COLLADA, glTF).

export class Camera extends Entity

Dodajte perspektivnu kameru u scenu i konfigurirajte njen 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

Enumerations

moveForward(distance)

Pomakne kameru naprijed duž njenog smjera gledanja za zadanu udaljenost.

moveForward(distance: number): void

Enumerations

distance number

Udaljenost za pomicanje naprijed. Negativne vrijednosti pomiču kameru natrag.

U izvoru, Camera nasljeđuje od Entity. Light također proširuje Camera, što znači Light objekti imaju sva svojstva kamere u hijerarhiji tipova; to odražava FBX model podataka gdje svjetla i kamere dijele zajednički bazni tip čvora.
Koristite ProjectionType konstante klase (ProjectionType.PERSPECTIVE, ProjectionType.ORTHOGRAPHIC) umjesto sirovih literalnih stringova radi sigurnosti tipa.
