Camera

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

Camera yra Entity kuris gali būti prijungtas prie Node kad apibrėžtų vaizdą scenoje. Ji palaiko tiek perspektyvines, tiek ortografinės projekcijas, valdomas projectionType savybę. Kameros parametrai saugomi 3D faile, kai scena išsaugoma formatu, kuris palaiko kameras (FBX, COLLADA, glTF).

export class Camera extends Entity

Pridėkite perspektyvinę kamerą į sceną ir sukonfigūruokite jos frustumą.

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)

Perkelia kamerą į priekį pagal jos žiūrėjimo kryptį nurodytu atstumu.

moveForward(distance: number): void

Šaltinyje, Camera paveldi iš Entity. Light taip pat plečia Camera, kas reiškia Light objektai turi visas kameros savybes tipų hierarchijoje; tai atspindi FBX duomenų modelį, kuriame šviesos šaltiniai ir kameros dalijasi bendru baziniu mazgo tipu.
Naudokite ProjectionType klasės konstantų (ProjectionType.PERSPECTIVE, ProjectionType.ORTHOGRAPHIC) vietoj tiesioginių eilutės literalių dėl tipų saugumo.
