GLTF 1.0

glTF (GL Transmission Format) is a 3D file format that stores 3D model information in JSON format. The use of JSON minimizes the size of 3D assets and the runtime processing required to decompress and use these assets. It is used by applications for efficient transmission and loading of 3D scenes and models. glTF was developed by the Khronos Group 3D Format Working Group and is also described by its creators as the JPEG of 3D.

The glTF file format defines a scalable, universal publishing format for 3D content tools and services, simplifying the creative workflow and enabling interoperable use of content across industries. The purpose of creating the glTF file format is to define a scalable, universal publishing format for 3D content tools and services, simplifying the creative workflow and enabling interoperable use of content across industries. It minimizes the runtime processing required by applications using WebGL and other APIs.
