.babylon — Babylon.js Scene Format
BabylonJS · 2014
It's a JSON file format for describing 3D scenes, primarily used with the Babylon.js JavaScript framework for web graphics.
Key Features
- JSON-based structure for easy parsing and web integration.
- Supports detailed scene elements: meshes, materials, textures, animations, lights, cameras.
- Designed for efficient loading and rendering in the Babylon.js JavaScript framework.
- Can be manually edited or programmatically generated and modified.
Best For
- Web-based 3D scenes using Babylon.js.
- Exporting from popular 3D modeling software.
- Interactive 3D content in browsers.
- Data interchange between 3D tools and web applications.
Less Ideal For
- Native desktop 3D application development.
- High-fidelity game development requiring complex shaders and physics engines.
- Archiving large, complex 3D projects long-term.
- Direct import into CAD or DCC software without conversion.
Common Use Cases
- Loading 3D models into web applications built with Babylon.js.
- Exporting scenes from 3D modeling software (like Blender) for web display.
- Creating interactive 3D experiences on websites.
- Web-based product configurators and visualizations.
- Educational tools and games requiring 3D graphics in a browser.
How to Open It
- Primarily loaded via the Babylon.js engine within a web browser using JavaScript.
- Can be opened and inspected in any text editor or JSON viewer to see its structure.
- Exported from 3D modeling software like Blender using specific exporters.
- Viewed using online Babylon.js scene viewers or custom web applications.
What is a .babylon file?
The .babylon file format is a JSON-based format used to describe 3D scenes. It stores information about meshes, materials, textures, lights, cameras, and animations within a scene. This format is designed to be easily parsed and used by the Babylon.js JavaScript framework, making it a popular choice for web-based 3D applications. It allows developers to export complex 3D scenes from various modeling software and load them efficiently into a web browser. The JSON structure makes it human-readable and editable to some extent, facilitating integration and customization.

Frequently Asked Questions
No, .babylon is a specific format developed for Babylon.js, while .gltf and .glb are industry-standard formats for 3D web content. You can convert between them.
Yes, since it's a JSON file, you can open it in a text editor or IDE and make edits, but be cautious to maintain the correct structure.
Yes, the .babylon format can store various types of animations, including position, rotation, scaling, and morph target animations.
Technical Details
The .babylon format is a plain text JSON file. It defines a scene graph structure, detailing all geometric data, material properties, animation curves, and camera/light configurations. Because it's JSON, it's highly extensible and easy to integrate with web technologies. It can also incorporate binary data for geometry or textures when optimized for performance, though the core definition remains in JSON.
