在Autodesk Forge中实现动画服务可以通过使用Three.js等JavaScript库来创建和渲染动画,同时调用Forge的API进行模型和数据管理。
以下是一个简单的示例,说明如何使用Three.js和Forge的API来实现动画服务:
import * as THREE from 'three';
import { API } from 'forge-api';
import { Viewer } from 'forge-viewer';
let scene = new THREE.Scene();
let camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;
let api = new API();
let viewer = new Viewer({api});
let model = await viewer.loadModel('urn:my-model-urn');
let data = await api.getData('my-data-url');
let geometry = new THREE.BoxGeometry();
let material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
let cube = new THREE.Mesh(geometry, material);
scene.add(cube);
function animate() {
requestAnimationFrame(animate);
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render(scene, camera);
}
animate();
let renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
