What is babylon.js?

Babylon.js is an open-source 3D game and rendering engine that runs directly in a web browser. The problem it solves is making it possible to build rich, interactive 3D experiences, games, simulations, product visualisers, virtual tours, without requiring users to install any software. It all runs inside the browser using WebGL, a web standard that lets browsers render 3D graphics using the device's graphics hardware. The engine provides all the building blocks you need for 3D: scenes, cameras, lights, meshes (the 3D shapes that make up objects), textures, animations, and physics. You set up a canvas element on a webpage, create a scene, add objects and lighting, and the engine handles the complex math of projecting 3D geometry onto a 2D screen and animating it at high frame rates. It also supports WebAudio for sound, and can import 3D models from tools like Blender, 3DS Max, and Maya. You would use Babylon.js if you are a developer building a browser-based game, an interactive product demo, an architectural walkthrough, or any other real-time 3D experience for the web. It comes with an interactive online playground for experimenting with the API without any local setup. The tech stack is TypeScript (which compiles to JavaScript), and it is installed via npm or loaded from a CDN.
