Camera

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

Camera ir Entity kas var tikt pievienots Node lai definētu skatpunktu ainas. Tas atbalsta gan perspektīvas, gan ortogrāfiskās projekcijas, ko kontrolē projectionType īpašība. Kameras parametri tiek saglabāti 3D failā, kad aina tiek saglabāta formātā, kas atbalsta kameras (FBX, COLLADA, glTF).

export class Camera extends Entity

Pievienojiet perspektīvu kameru ainai un konfigurējiet tās frustumu.

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

Avotā, Camera manto no Entity. Light arī paplašina Camera, kas nozīmē Light objektiem ir visas kameras īpašības tiphierarhijā; tas atspoguļo FBX datu modeli, kur gaismas avoti un kameras koplieto kopīgu pamata mezgla tipu.
Izmantojiet ProjectionType klases konstantes (ProjectionType.PERSPECTIVE, ProjectionType.ORTHOGRAPHIC) nevis neapstrādātus virknes literālus tipa drošībai.
