GL Transmission Format · model/gltf+json · .gltf .glb

Overview

glTF is the Khronos standard for transmitting 3D scenes to WebGL and game engines. It preserves scene graphs, PBR materials, textures, and animations in a compact package designed for fast loading.

Typical use cases

  • Web 3D
  • Real-time rendering
  • AR/VR assets
  • Game asset exchange

Advantages

  • Designed for web 3d
  • None storage
  • Open standard specification
  • Browser support: Rendered natively by many WebGL tools and platforms

Disadvantages

  • Complex scenes need tooling
  • Binary variant is a separate file
  • Not a CAD exchange format

How to open or use it

Open glTF files with an application that supports model/gltf+json. Editable in modern 3D tools and engines. For delivery, use a viewer or converter that reads gltf, glb.
