Babylon.js: JavaScript 3D engine install routes, quick-start scene and learning tools

What it supplies: The README does not define the project in prose; it starts with a playground link for trying the Babylon.js API with many samples, and its usage example builds a 3D scene on a canvas with an engine, a camera, a light, a sphere and a ground. It points to the website for the complete list of supported features. Useful for: - Learn the API in the online playground and its samples. - Build a basic 3D scene in a web page with the quick-start code. - Test .babylon and glTF scenes in the sandbox, or export .babylon files from 3DS Max, Maya or Blender. First action: - Try the playground first, then follow the Getting Started documentation. - For a project, run npm install babylonjs --save, or use the ES6 packages for tree shaking. - With TypeScript, add babylonjs to the types list in tsconfig.json. - For quick experiments, load babylon.js from the CDN, but not in production. Prerequisites and limits: To build and develop the repository, the README requires Node.js 22.22.2 or newer on the Node 22 line, or 24.16.0 or newer on the Node 24 line, and npm 11.18.0 or newer. It says these are development-tool requirements that do not change the runtime requirements of the published libraries, which it does not list. - The CDN is meant for learning and small experiments, not production. - The README gives no feature list or runtime requirements; it points to the website for features. - The Unity 5 exporter is deprecated. This README does not state a licence in the text read here, so check the repository's licence file before use or redistribution. Models and textures you load carry their own rights. Written from the README text only. Statements are as the README gives them; nothing was installed or run and no scene was rendered. Based on README text only; the documentation, website feature list and any licence file were not read. No install or run was made.
