Camera

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

Camera adalah satu Entity yang boleh dilampirkan kepada Node untuk menentukan sudut pandang dalam adegan. Ia menyokong kedua-dua proyeksi perspektif dan ortografik, dikawal oleh projectionType sifat. Parameter kamera disimpan dalam fail 3D apabila adegan disimpan ke format yang menyokong kamera (FBX, COLLADA, glTF).

export class Camera extends Entity

A3DObject ← SceneObject ← Entity ← Camera

ImageRenderOptions

Tambah kamera perspektif ke dalam adegan dan konfigurasikan frustumnya.

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

Dalam sumber, Camera mewarisi dari Entity. Light juga meluaskan Camera, yang bermakna Light objek mempunyai semua sifat kamera dalam hierarki jenis; ini mencerminkan model data FBX di mana lampu dan kamera berkongsi jenis nod asas yang sama.
Gunakan ProjectionType pemalar kelas (ProjectionType.PERSPECTIVE, ProjectionType.ORTHOGRAPHIC) daripada literal rentetan mentah untuk keselamatan jenis.
