Hello World.

function createScene() {
    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('camera', 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 sphere
    var sphere = BABYLON.MeshBuilder.CreateSphere('sphere', {segments:16, diameter:2}, scene);
    sphere.position.y = 1;

    var ground = BABYLON.Mesh.CreateGround('ground1', {height:6, width:6, subdivisions: 2}, scene);
    return scene;

How to do cool stuff in WebGL

var light = new BABYLON.PointLight(
    "pointLight", 
    new BABYLON.Vector3(1, 10, 1), 
    scene
);

light.diffuse = new BABYLON.Color3(1, 0, 0);
light.specular = new BABYLON.Color3(0, 1, 0);

var scene = new BABYLON.Scene(engine);
var gravityVector = new BABYLON.Vector3(0,-9.81, 0);
var physicsPlugin = new BABYLON.CannonJSPlugin();
scene.enablePhysics(gravityVector, physicsPlugin);

particleSystem.particleTexture = new BABYLON.Texture(
    "some-image-sprite.png", 
    scene
);
particleSystem.textureMask = new BABYLON.Color4(0.3, 0.9, 0.8, 1.0);

var fountain = BABYLON.Mesh.CreateBox("foutain", 1.0, scene);

var particleSystem = new BABYLON.ParticleSystem(
    "particles", 
    2000, 
    scene
);

particleSystem.emitter = fountain;
