Babylon.js vs WebGL: Separating Fact from Fiction

For developers prioritizing API accessibility and versatility, Babylon.js stands unmatched with its offerings in virtual worlds, physiognomic modelling and animated complexities. However, if your project calls for a cross-platform, low-level 3D graphics API with straightforward integration into browsers, then WebGL is your go-to.

Key Differences Between Babylon.js and WebGL

• Babylon.js is a real-time 3D engine developed largely by Microsoft, whereas WebGL is a low-level 3D graphics API created by Khronos Group.
• WebGL offers direct interface integration into browsers with a focus on cross-platform compatibility. Babylon.js, however, focuses on polygon modelling and plug-in physics engines.
• Both Babylon.js and WebGL are written in JavaScript, but Babylon.js is also written in TypeScript and is compiled into JavaScript.
• Babylon.js uses Apache License 2.0 while WebGL is an open-source enabling direct interaction with HTML documentation elements.

What Is Babylon.js and Who’s It For?

Babylon.js, a real time 3D engine, was incepted by David Catuhe and further developed by Microsoft and a myriad of other contributors. This 3D engine proliferates remarkable 3D graphics via HTML5 through web browsers. Initially released in 2013, the engine demonstrates sturdy stability with its latest release being 5.3.0 and is available on Github under the Apache License 2.0. Babylon.js caters to an array of applications; from urban underground infrastructure modelling to modelling historic sites and military training.

Pros of Babylon.js

• Availability of GitHub source code under Apache License 2.0
• Extensive contributions from more than 190 contributors
• Wide usage in various sectors: virtual worlds, visualization, and education.

Cons of Babylon.js

• Limited use of constructive solid geometry
• Reliance on plug-in physics engines
• Dependency on HTML5 and WebGL supporting browsers

What Is WebGL and Who’s It For?

WebGL stands tall as a low-level 3D graphics API linked to ECMAScript via HTML5 Canvas and is forged on the anvil of OpenGL ES. Providing 3D splendor to the web without plugins, WebGL is seamlessly incorporated into browsers. WebGL brings to the table an API that offers omnipresent compatibility, GPU 3D acceleration, native GLSL support, and DOM interface integration. Despite its OpenGL origins, WebGL conveys a set of unique qualities depending on the platform it is run on.

Pros of WebGL

• Serves cross-platform compatibility
• Delivers GPU 3D acceleration and native GLSL support
• Direct interaction with other HTML Document elements

Cons of WebGL

• Dependent on implementations that can be relatively slower and not comprehensive
• Quality issues led most games to opt for D3D10+
• Runs on different technologies based on the platform

Babylon.js vs WebGL: Pricing

Babylon.js and WebGL, both accessible technologies, remain open-source with no explicit pricing detailed.

Babylon.js

Developed as a free, open-source project by Microsoft, Babylon.js’s source code is freely available under the Apache License 2.0 on GitHub. The use of the technology does not entail any direct cost. Its robust features and seamless integration with HTML5 and WebGL-supported browsers make it a cost-free choice for 3D graphics-related projects.

WebGL

WebGL is an open standard, controlled by web browsers and available without charge. As an open-source API, it runs without a JVM. WebGL provides 3D graphics capabilities directly in the browser and does not require a specific paid technology. Its adoption requires neither licensing fees nor royalties, making it a free-of-cost option for developers aiming to furnish web applications with 3D graphics.

Code Examples for Babylon.js & WebGL

Babylon.js

A simplified example of creating a reflective sphere in Babylon.js. Babylon.JS, Cannon.js and a compatible browser are essential for optimum functioning of the code.

var canvas=document.getElementById("renderCanvas");var engine=new BABYLON.Engine(canvas,true);var createScene=function(){var scene=new BABYLON.Scene(engine);var camera=new BABYLON.ArcRotateCamera("Camera",Math.PI/2,1.0,110,BABYLON.Vector3.Zero(),scene);camera.attachControl(canvas,true);var light1=new BABYLON.HemisphericLight("light1",new BABYLON.Vector3(1,1,0),scene);var sphere=BABYLON.Mesh.CreateSphere("sphere1",16,2,scene);var sphereMaterial=new BABYLON.StandardMaterial("sphereMat",scene);sphereMaterial.diffuseColor=new BABYLON.Color3(0.5,0.5,1);sphereMaterial.specularColor=new BABYLON.Color3(0.5,0.5,1);sphereMaterial.emissiveColor=BABYLON.Color3.Blue();sphere.material=sphereMaterial;return scene;};var scene=createScene();engine.runRenderLoop(function(){scene.render();});window.addEventListener("resize",function(){engine.resize();});

WebGL

Here’s a WebGL code snippet for creating a 2D square and a working shader program. WebGL enabled browser is crucial along with WebGL API for optimum performance.

var canvas=document.querySelector("canvas");var gl=canvas.getContext("webgl");if(!gl){alert("WebGL not supported");}var vertexShader=gl.createShader(gl.VERTEX_SHADER);gl.shaderSource(vertexShader,vertexShaderText);gl.compileShader(vertexShader);if(!gl.getShaderParameter(vertexShader,gl.COMPILE_STATUS)){alert(gl.getShaderInfoLog(vertexShader));}var fragmentShader=gl.createShader(gl.FRAGMENT_SHADER);gl.shaderSource(fragmentShader,fragmentShaderText);gl.compileShader(fragmentShader);if(!gl.getShaderParameter(fragmentShader,gl.COMPILE_STATUS)){alert(gl.getShaderInfoLog(fragmentShader));}var program=gl.createProgram();gl.attachShader(program,vertexShader);gl.attachShader(program,fragmentShader);gl.linkProgram(program);if(!gl.getProgramParameter(program,gl.LINK_STATUS)){alert(gl.getProgramInfoLog(program));}gl.useProgram(program);

The Final Showdown: Babylon.js or WebGL?

In the grand arena of technology, two giants face off, Babylon.js and WebGL. Let’s dissect our verdict per audience segment.

Web Developers

Web Developers, Babylon.js is your optimal choice as it provides rapid 3D modeling and rendering within HTML5-supported browsers with an easy-to-access API. Coupled with its TypeScript origins, it provides a modern, evolving, yet omnipresent platform unlike any other.

Game Developers

For Game Developers, the battle rages on but WebGL takes the throne. With an API offering cross-platform compatibility and native GLSL support, it is tailored for any dedicated game dev’s 3D graphical demands.

AR/VR Creators

Babylon.js, undeniably, is the preferred choice for AR/VR Creators. With its plug-in physics engines and skeletal blend weights for animation, it sets the stage for delivering immersive AR/VR experiences.

Open-source Enthusiasts

Open-source Enthusiasts rejoice, both titans bring to the table open-source pedigree. WebGL, however, sets itself apart with its wide browser support, being a de-facto standard in mobile browser 3D graphics.

Despite their shared 3D prowess, Babylon.js, a seasoned 3D engine offering seamless 3D rendering in HTML5, excels for web and AR/VR development, while WebGL’s cross-platform capabilities crown it the champion for game development.
