刚刚嵌入过Three.js，我们又来镶嵌Babylon.js。话说当年玩具型的小东西，几年不看都长这么大了。还具备了编辑器，而且同时支持在线和桌面（虽然今天跑桌面遇到问题，还没解掉）。文档也很丰富。真是不能小觑了。当年的Unity3d，不也曾经是玩具吗？
在WordPress里面内嵌类似Babylon.js，或者Three.js，只要使用WordPress的Custom HTML块即可（我使用的是Block编辑方式）。比如，上面的3D场景显示的代码，就是一段用<pre></pre>包起来的自定义html代码。全部代码（在一个Custom HTML中）如下：
<pre>
<canvas id="renderCanvas" width="640" height="480"></canvas>
<script src="https://cdn.bootcss.com/babylonjs/4.0.3/babylon.js"></script>
<script>
// Get the canvas DOM element
var canvas = document.getElementById('renderCanvas');
// Load the 3D engine
var engine = new BABYLON.Engine(canvas, true, {preserveDrawingBuffer: true, stencil: true});
// CreateScene function that creates and return the scene
var createScene = function(){
// Create a basic BJS Scene object
var scene = new BABYLON.Scene(engine);
// Create a FreeCamera, and set its position to {x: 0, y: 5, z: -10}
var camera = new BABYLON.FreeCamera('camera1', new BABYLON.Vector3(0, 5, -10), scene);
// Target the camera to scene origin
camera.setTarget(BABYLON.Vector3.Zero());
// Attach the camera to the canvas
camera.attachControl(canvas, false);
// Create a basic light, aiming 0, 1, 0 - meaning, to the sky
var light = new BABYLON.HemisphericLight('light1', new BABYLON.Vector3(0, 1, 0), scene);
// Create a built-in "sphere" shape; its constructor takes 6 params: name, segment, diameter, scene, updatable, sideOrientation
var sphere = BABYLON.Mesh.CreateSphere('sphere1', 16, 2, scene, false, BABYLON.Mesh.FRONTSIDE);
// Move the sphere upward 1/2 of its height
sphere.position.y = 1;
// Create a built-in "ground" shape; its constructor takes 6 params : name, width, height, subdivision, scene, updatable
var ground = BABYLON.Mesh.CreateGround('ground1', 6, 6, 2, scene, false);
// Return the created scene
return scene;
}
// call the createScene function
var scene = createScene();
// run the render loop
engine.runRenderLoop(function(){
scene.render();
});
// the canvas/window resize event handler
window.addEventListener('resize', function(){
engine.resize();
});
</script>
</pre>
注：上面的3D场景可以通过鼠标控制转动。
