Hello World

你可能需要下載 three.js 並更改下面的指令碼源。

此連結下有許多更高階的示例。

HTML：

<html>
<head>
    <meta charset=utf-8>
    <title>My first Three.js app</title>
    <style>
        body { margin: 0; }
        canvas { width: 100%; height: 100% }
    </style>
</head>
<body>
<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r83/three.js"></script>
    <script>
        // Our JavaScript will go here.
    </script>
</body>

JavaScript 中的靜態多維資料集的基本場景：

var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 );

var renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );

var geometry = new THREE.BoxGeometry( 1, 1, 1 );
var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
var cube = new THREE.Mesh( geometry, material );
scene.add( cube );

camera.position.z = 5;

要實際看到任何東西，我們需要一個 Render() 迴圈：

function render() {
    requestAnimationFrame( render );
    renderer.render( scene, camera );
}
render();
