Camera

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

Camera är en Entity som kan fästas på en Node för att definiera en synvinkel i scenen. Den stöder både perspektiv- och ortografiska projektioner, styrda av projectionType egenskapen. Kameraparametrar lagras i 3D-filen när scenen sparas till ett format som stöder kameror (FBX, COLLADA, glTF).

export class Camera extends Entity

Lägg till en perspektivkamera i en scen och konfigurera dess 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

I källkoden, Camera ärver från Entity. Light utökar också Camera, vilket betyder Light objekt har alla kamerainställningar i typ‑hierarkin; detta speglar FBX-datamodellen där ljus och kameror delar en gemensam basnodtyp.
Använd ProjectionType klasskonstanter (ProjectionType.PERSPECTIVE, ProjectionType.ORTHOGRAPHIC) istället för råa strängliteral för typ‑säkerhet.
