html代码：

<!DOCTYPE html>
<html lang="en">
	<head>
		<title>6图版全景图</title>
		<meta charset="utf-8">
		<meta name="viewport" content="width=device-width, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0">

	<body>

		<div id="container"></div>
	</body>
</html>

Js代码：

	<script type="module">
			import * as THREE from 'three.module.js';

			import { OrbitControls } from 'OrbitControls.js';

			let container;

			let camera, scene, renderer;

			let pointLight;

			init();
			animate();

			function init() {
				container = document.createElement( 'div' );
				document.body.appendChild( container );

				camera = new THREE.PerspectiveCamera( 50, window.innerWidth / window.innerHeight, 1, 5000 );
				camera.position.z = 2000;

				//cubemap
				const path = 'images/';
				const format = '.jpg';
				const urls = [
					path + 'px' + format, path + 'nx' + format,
					path + 'py' + format, path + 'ny' + format,
					path + 'pz' + format, path + 'nz' + format
				];

				const reflectionCube = new THREE.CubeTextureLoader().load( urls );
				refractionCube.mapping = THREE.CubeRefractionMapping;

				scene = new THREE.Scene();
				scene.background = reflectionCube;

				//lights
				const ambient = new THREE.AmbientLight( 0xffffff );
				scene.add( ambient );

				pointLight = new THREE.PointLight( 0xffffff, 2 );
				scene.add( pointLight );

			

				//renderer
				renderer = new THREE.WebGLRenderer();
				renderer.setPixelRatio( window.devicePixelRatio );
				renderer.setSize( window.innerWidth, window.innerHeight );
				container.appendChild( renderer.domElement );

				//controls
				const controls = new OrbitControls( camera, renderer.domElement );
				controls.enableZoom = false;
				controls.enablePan = false;
				controls.minPolarAngle = Math.PI / 4;
				controls.maxPolarAngle = Math.PI / 1.5;


				window.addEventListener( 'resize', onWindowResize, false );

			}

			function onWindowResize() {

				camera.aspect = window.innerWidth / window.innerHeight;
				camera.updateProjectionMatrix();

				renderer.setSize( window.innerWidth, window.innerHeight );

			}

			function animate() {

				requestAnimationFrame( animate );
				render();

			}

			function render() {

				renderer.render( scene, camera );

			}

		</script>
