系列博文-Three.js入门指南(张雯莉)-静态demo和three.js功能概览

發(fā)布時(shí)間：2025/3/15 编程问答 17 豆豆

生活随笔收集整理的這篇文章主要介紹了系列博文-Three.js入门指南(张雯莉)-静态demo和three.js功能概览小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

一：一個(gè)最簡單的靜態(tài)DEMO

//body加載完后觸發(fā)init() //WebGL的渲染是需要HTML5 Canvas元素的，你可以手動(dòng)在HTML的<body>部分中定義Canvas元素，或者讓Three.js幫你生成。這兩種選擇一般沒有多大差別，我們在此手動(dòng)在HTML中定義： <body οnlοad="init()"><canvas id="mainCanvas" width="400px" height="300px" ></canvas> </body> <script>function init() {var renderer = new THREE.WebGLRenderer({canvas: document.getElementById('mainCanvas')});renderer.setClearColor(0x000000); var scene = new THREE.Scene(); var camera = new THREE.PerspectiveCamera(45, 4 / 3, 1, 1000);camera.position.set(0, 0, 5);scene.add(camera); var cube = new THREE.Mesh(new THREE.CubeGeometry(1, 2, 3),new THREE.MeshBasicMaterial({color: 0xff0000}));scene.add(cube); renderer.render(scene, camera); }</script>
