Three.js - OrbitControls不起作用

Question

如果我运行脚本,控制台会显示"THREE.OrbitControls不是构造函数".

我错了什么？我使用了手册中的相同代码.

var controls;
    controls = new THREE.OrbitControls( camera );
    controls.addEventListener( 'change', render );

var render = function () {
    requestAnimationFrame( render );
    renderer.render(scene, camera);
                //Hier wird die Größe des Fensters manipuliert!
    renderer.setSize(window.innerWidth - 20, window.innerHeight - 20);                  

};

    var animate = function () {
        requestAnimationFrame( animate );
        controls.update();                  
    };


var geometry1 = new THREE.BoxGeometry( 10, 10, 10);
var material = new THREE.MeshPhongMaterial( {specular: "#fdfb57", color: "#d8d613", emissive: "#6b6a0d", side: THREE.DoubleSide} );
var box = new THREE.Mesh(geometry1, material);


scene.add(box);   

camera.position.z = 50;


render();   
animate();

Answer 1

您必须明确包含OrbitControls在您的申请中.

<script src="js/controls/OrbitControls.js"></script>

另外,请OrbitControls仔细阅读three.js 示例中的注释,以便了解何时使用

controls.addEventListener( 'change', render ); // add this only if there is no animation loop (requestAnimationFrame)

何时使用

controls.update(); // required if controls.enableDamping = true, or if controls.autoRotate = true

three.js r.72

Answer 2

我在webpack构建three库时遇到了同样的问题

var THREE = require('three')
THREE.OrbitControls === undefined  // true

解决方案,安装第三方轨道控制

npm install three-orbit-controls

详情请访问:https://github.com/mattdesl/three-orbit-controls

然后将上面的代码片段更改为

var THREE = require('three')
var OrbitControls = require('three-orbit-controls')(THREE)
OrbitControls === undefined  // false

好吧,不是最好的例子,但是当应用代替时THREE.OrbitControls,它工作得很好;)

https://github.com/nicolaspanel/three-orbitcontrols-ts：

npm install --save three-orbitcontrols-ts
import { OrbitControls } from 'three-orbitcontrols-ts'

orbitcontrols 应该分开安装在角度，这个问题困扰了我几天。
