Three 学习日志(四)—— 相机控件
一、引入相机控件
<script type="importmap">
{
"imports": {
"three": "../build/three.module.js",
"three/addons/": "../examples/jsm/"
}
}
script>
<script type="module">
import { OrbitControls } from 'three/addons/controls/OrbitControls.js';
script>
二、开启相机控件监听
const controls = new OrbitControls(camera, renderer.domElement);
controls.addEventListener('change', function () {
renderer.render(scene, camera);
});
三、效果展示

四、完整代码
