vue中利用three.js实现全景图的完整示例

粗暴一点,直接上代码:

第一步:

通过指令下载three.js

npm install three -S

第二步:

在组件中引用

import * as THREE from 'three'

第三步:

html部分

<div></div>

js部分

<script> import * as THREE from 'three'; var camera; var renderer; var scene; export default { name: 'panorama', data() { return { bigImg: require("../../../../../images/项目案例/001.jpg"),//全景图图片路径 } }, mounted() { // 调用全景图函数 this.$nextTick(() => { this.init(); this.animate(); }) }, methods: { // 全景图配置函数--------------- init() { var container = document.getElementById('container'); // 创建渲染器 renderer = new THREE.WebGLRenderer(); renderer.setPixelRatio(window.devicePixelRatio); // 设置画布的宽高 renderer.setSize(window.innerWidth, window.innerHeight); // 判断容器中子元素的长度 let childs = container.childNodes; if (container.childNodes.length > 0) { container.removeChild(childs[0]); container.appendChild(renderer.domElement); } else { container.appendChild(renderer.domElement); } // container.appendChild(renderer.domElement); // 创建场景 scene = new THREE.Scene(); // 创建相机 camera = new THREE.PerspectiveCamera(90, window.innerWidth / window.innerHeight, 0.1, 100); camera.position.set(0, 0, 0); var material = new THREE.MeshBasicMaterial();//材质 var texture = new THREE.TextureLoader().load(this.bigImg); material.map = texture; var skyBox = new THREE.Mesh( new THREE.SphereBufferGeometry(100, 100, 100), material ); skyBox.geometry.scale(1, 1, -1); scene.add(skyBox); window.addEventListener('resize', this.onWindowResize, false); var bMouseDown = false; var x = -1; var y = -1; // 添加鼠标事件 container.onmousedown = function (event) { event.preventDefault();//取消默认事件 x = event.clientX; y = event.clientY; bMouseDown = true; } container.onmouseup = function (event) { event.preventDefault(); bMouseDown = false; } container.onmousemove = function (event) { event.preventDefault(); if (bMouseDown) { skyBox.rotation.y += -0.005 * (event.clientX - x); skyBox.rotation.x += -0.005 * (event.clientY - y); if (skyBox.rotation.x > Math.PI / 2) { skyBox.rotation.x = Math.PI / 2 } if (skyBox.rotation.x < -Math.PI / 2) { skyBox.rotation.x = -Math.PI / 2 } x = event.clientX; y = event.clientY; } } container.onmousewheel = function (event) { event.preventDefault(); if (event.wheelDelta != 0) { camera.fov += event.wheelDelta > 0 ? 1 : -1; if (camera.fov > 150) { camera.fov = 150; } else if (camera.fov < 30) { camera.fov = 30; } camera.updateProjectionMatrix(); } } }, onWindowResize() { // 窗口缩放的时候,保证场景也跟着一起缩放 camera.aspect = window.innerWidth / window.innerHeight; camera.updateProjectionMatrix(); renderer.setSize(window.innerWidth, window.innerHeight); }, animate() { requestAnimationFrame(this.animate); renderer.render(scene, camera); } }, } </script>
