Babylon.js vs A-Frame: Pricing

Both Babylon.js and A-Frame offer open-source software solutions, rendered freely available under the Apache License 2.0 and MIT License, respectively.

Babylon.js

Babylon.js, a robust real-time 3D engine, is an open-source software developed by Microsoft and other contributors. Leveraging the distribution premise of the Apache License 2.0, developers can freely access the GitHub source code to address their project needs without any pricing strings attached.

A-Frame

Similar to Babylon.js, A-Frame—a viable JavaScript framework for VR experiences—is also open-source. Developed by the Mozilla VR team, A-Frame is under the MIT License, assuring developers of unrestricted, free usage. Supermedium, with a team of Google developers, maintains the framework, keeping the code base accessible to the global development community without any pricing demands.

Code Examples for Babylon.js & A-Frame

Babylon.js

This vibrant demonstration leverages Babylon.js to create a groundbreaking spectacle: A dancing 3D cube that lights-up different colors, vis-a-vis the music beats. This exhibition mandates a Babylon.js import and a basic understanding of JavaScript.

    var scene = new BABYLON.Scene(engine);
    var camera = new BABYLON.FreeCamera("camera", new BABYLON.Vector3(0, 5, -10), scene);
    var light = new BABYLON.HemisphericLight("light", new BABYLON.Vector3(0, 1, 0), scene);
    var mesh = BABYLON.MeshBuilder.CreateBox("box", {}, scene);
    var material = new BABYLON.StandardMaterial("material", scene);
    mesh.material = material;

    scene.onBeforeRenderObservable.add(() => {
        mesh.rotation.y+= 0.01;
        mesh.rotation.x+= 0.01;
        if(Math.round(scene.getEngine().getFps())%60 === 0){
            material.diffuseColor = new BABYLON.Color3(Math.random(), Math.random(), Math.random());
        }
    });

A-Frame

Animate a solar system! Harnessing A-Frame, this code delineates a miniature solar system with sun, moon, and earth revolving in real-time. You’ll require A-Frame library inclusion for this celestial spectacle.

    <a-scene>
        <a-sphere id="sun" radius="1" color="yellow" position="0 2 0"></a-sphere>
        <a-entity id="earthOrbit" position="0 2 0">
            <a-sphere id="earth" radius="0.5" color="blue" position="5 0 0">
                <a-entity id="moonOrbit">
                    <a-sphere id="moon" radius="0.25" color="white" position="2 0 0"></a-sphere>
                </a-entity>
            </a-sphere>
        </a-entity>
        <a-animation id="earthSpin" attribute="rotation" dur="10000" to="0 360 0" repeat="indefinite"></a-animation>
        <a-animation id="moonSpin" attribute="rotation" dur="10000" to="0 360 0" repeat="indefinite"></a-animation>
    </a-scene>
