学习 three.js (Part 1: hello world)
ref: Installation – three.js docs
操作步骤略有不同:
-
yarn create vite, project: hello, framework选择Vanilla - code打开hello, 在terminal中运行yarn安装依赖，然后yarn dev运行，打开可以看到vite默认页面
-
yarn add three - 然后copy three.js docs中index.html代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My first three.js app</title>
<style>
body {
margin: 0;
}
</style>
</head>
<body>
<script type="module" src="/main.js"></script>
</body>
</html>
- copy main.js代码
import * as THREE from 'three';
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
const renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.setAnimationLoop( animate );
document.body.appendChild( renderer.domElement );
const geometry = new THREE.BoxGeometry( 1, 1, 1 );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const cube = new THREE.Mesh( geometry, material );
scene.add( cube );
camera.position.z = 5;
function animate() {
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render( scene, camera );
}
打开浏览器看到green cube, 收工。
注:
- vite代替了create-react-app
- 不建议使用script tag引用script，几次都失败
