3.Vue引入ThreeJS

近期项目需要做3D效果，因为以前没做过，所以准备学习Three.js来完成项目需求，

可是找了很多地方都只有很少的一些在Vue中使用three.js的文章

经过自己的整理，将详细步骤分享给大家

1.首先利用npm安装three.js,具体操作代码如下：

npm install three

若安装了淘宝镜像，则操作命令为：

cnpm install three

2.接下来利用npm安装轨道控件插件：

npm install three-orbit-controls

3.接下来安装加载.obj和.mtl文件的插件：

npm i --save three-obj-mtl-loader

4.安装渲染器插件：

npm i --save three-css2drender

安装好以后，在页面中引入three.js并使用，在所调用页面引入的代码为：

import * as Three from 'three'

import * as Three from "three";
  import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js'
  import { ConvexGeometry } from 'three/examples/jsm/geometries/ConvexGeometry.js'
  import {BufferGeometryUtils} from 'three/examples/jsm/utils/BufferGeometryUtils.js'
  // import { OBJLoader, MTLLoader } from 'three-obj-mtl-loader'
  import {OBJLoader} from 'three/examples/jsm/loaders/OBJLoader.js';
  import {MTLLoader} from 'three/examples/jsm/loaders/MTLLoader.js';

<template>
	<div>
		<div id="container"></div>
	</div>
</template>
<script>
	import * as Three from "three";
	export default {
		name: "ThreeTest",
		data() {
			return {
				camera: null,
				scene: null,
				renderer: null,
				mesh: null,
			};
		},
		methods: {
			init() {
				let container = document.getElementById("container");
				this.camera = new Three.PerspectiveCamera(
					70,
					container.clientWidth / container.clientHeight,
					0.01,
					1000
				);
				this.camera.position.z = 0.6;
				this.scene = new Three.Scene();
				let geometry = new Three.CylinderBufferGeometry(0.2, 0.2, 0.2);
				let material = new Three.MeshNormalMaterial();
				this.mesh = new Three.Mesh(geometry, material);
				this.scene.add(this.mesh);
				this.renderer = new Three.WebGLRenderer({
					antialias: true
				});
				this.renderer.setSize(container.clientWidth, container.clientHeight);
				container.appendChild(this.renderer.domElement);
			},
			animate() {
				requestAnimationFrame(this.animate);
				this.mesh.rotation.x += 0.01;
				this.mesh.rotation.y += 0.02;
				this.renderer.render(this.scene, this.camera);
			},
		},
		mounted() {
			this.init();
			this.animate();
		},
	};
</script>

<style scoped>
	#container {
		height: 400px;
	}
</style>

注意相关变量的定义容器大小的定义，接下来可以运行当前vue项目，并在浏览器中查看当前效果：
