## What it is
The official Khronos Group repository for the glTF (GL Transmission Format) specification, a royalty-free standard for efficiently transmitting and loading 3D scenes and models. It hosts the glTF 2.0 specification, extension registry, quick reference guides, and sample assets for developers and content creators.

## Use cases
- learn the glTF 2.0 specification for 3D asset delivery
- find the right glTF extension for my 3D content
- validate how my 3D models should be structured for runtime loading
- download sample glTF assets for testing a 3D engine
- understand how to export 3D models from Blender to a web-friendly format
- implement a glTF loader in my game engine

## When to choose
- you need the authoritative glTF specification or extension registry
- you are implementing a glTF loader or exporter and need reference material
- you want sample 3D assets to test rendering pipelines

## When to avoid
- you need a runnable library or tool for loading glTF files at runtime - use ecosystem implementations instead
- you want a 3D engine or viewer rather than format documentation

## Facets
- artifact type: learning-resource
- maturity: stable
- function: documentation
- domain: graphics, web-development, developer-tools
- platform: cross-platform
- tags: gltf, 3d-assets, specification, khronos, asset-delivery, 3d-models, game-development
