Die*_*ani 3 javascript three.js
我试图将轨道控制添加到我的场景中，但没有成功。下面的代码不断给我一个错误Uncaught TypeError: THREE.OrbitControls is not a constructor。我尝试了在网上遇到的不同解决方案，但错误仍然存在。我究竟做错了什么？
伪代码
先感谢您。

var camera = new THREE.PerspectiveCamera(75, 320 / 240, 1, 1000);
camera.position.set(250, 200, 250);
camera.lookAt(0, 0, 0);
// add controls for the camera
var controls = new THREE.OrbitControls(camera);
var geometry = new THREE.PlaneGeometry(100, 50);
var material = new THREE.MeshBasicMaterial( { color: 0xFFFFFF } );
var plane = new THREE.Mesh( geometry, material );
scene.add( plane );
camera.position.z = 200;
var animate = function () {
requestAnimationFrame( animate );
controls.update();
// plane.rotation.x += 0.01;
// plane.rotation.y += 0.01;
renderer.render( scene, camera );
};
animate();
您的 codepen 中存在问题。当您OrbitControls通过 ES6 导入导入时，没有必要使用THREE命名空间。所以当做这样的事情时：
import { OrbitControls } from "https://threejs.org/examples/jsm/controls/OrbitControls.js";
你必须OrbitControls像这样创建：
controls = new OrbitControls( camera, renderer.domElement );
