Code Examples for Babylon.js & PixiJS

Babylon.js: Creating a Stylized Earth

In this Babylon.js code snippet, we’ll employ an advanced technique to visually enrich the rendition of our planet Earth. It will add diffusion and specular textures, improving the bland look of a normal sphere. To execute this, have Babylon.js v4.2.0 or higher installed.

            var canvas = document.getElementById('renderCanvas');
            var engine = new BABYLON.Engine(canvas, true);
            var scene = new BABYLON.Scene(engine);
            var camera = new BABYLON.ArcRotateCamera("camera", -Math.PI / 2, Math.PI / 3, 3, new BABYLON.Vector3(0, 0, 0), scene);
            camera.attachControl(canvas, true);

            BABYLON.SceneLoader.ImportMeshAsync("", "textures/", "earth.babylon", scene).then(function () {
                var light = new BABYLON.HemisphericLight("light", new BABYLON.Vector3(0, 1, 0), scene);
                scene.getMeshByName("earth").position.y -= 0.2;
            });

            engine.runRenderLoop(function () {
                scene.render();
            });

PixiJS: Creating a Particle System

This PixiJS piece of code implements a basic particle system. Particles give motion and life to static images, a nice asset in any developer’s repertoire. Essential prerequisites include PixiJS v5.3.3, along with a local server for JSON file hosting.

            var app = new PIXI.Application({width: 800, height: 600});
            document.body.appendChild(app.view);

            PIXI.Loader.shared.add("images/particle.json").load(setup);

            function setup() {
                var particleTexture = PIXI.Texture.from("images/particle.png");
                var config = PIXI.Loader.shared.resources["images/particle.json"].data;
                var emitter = new PIXI.particles.Emitter(
                    app.stage,
                    ,
                    config
                );

                var elapsed = Date.now();
                app.ticker.add(function() {
                    var now = Date.now();
                    emitter.update((now - elapsed) * 0.001);
                    elapsed = now;
                });
            }
