<head>
<title>Babylon.js Example</title>
<script src="https://cdn.babylonjs.com/babylon.js"></script>
</head>
<body>
<canvas id="renderCanvas"></canvas>
<script>
const canvas = document.getElementById("renderCanvas");
const engine = new BABYLON.Engine(canvas, true);
const scene = new BABYLON.Scene(engine);
const camera = new BABYLON.ArcRotateCamera("Camera", Math.PI / 2, Math.PI / 2, 2, BABYLON.Vector3.Zero(), scene);
camera.attachControl(canvas, true);
const light = new BABYLON.HemisphericLight("light1", new BABYLON.Vector3(1, 1, 0), scene);
const box = BABYLON.MeshBuilder.CreateBox("box", {}, scene);
engine.runRenderLoop(() => scene.render());
</script>
</body>
</html>
Save this file and open it in a browser to see your spinning cube in action!
