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

js部分

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);

}

},

}
