glTF

The Graphics Language Transmission Format was designed as an interoperable format for loading scenes and models created with 3D tools, in modern applications. The glTF format is a JSON-based text format and is accompanied by binary data (.bin) for geometry, animations, and other associated data; and raster images (.jpg; .png) for textures.
There are two versions of glTF: glTF 1.0, first released in October 2015; and glTF 2.0, released in June 2017. Version 2.0 is a significant upgrade from version 1.0 and is aimed at better support from applications. With the increasing adoption of version 2.0, version 1.0 seems to have become obsolete.

glb is the extension for binary glTF: a container format that collects the glTF and its associated data into a single file. Binary glTF was introduced as an extension for glTF 1.0 and was incorporated in the glTF 2.0 specification.

glTF is being developed in an open project by the non-profit organization Khronos Group.

glTF 2.0 is a preferred format for file type 3D.
glb is a preferred format for file type 3D on the condition that it is based on glTF 2.0.
glTF 1.0 and glb based on glTF 1.0 are non-preferred formats for file type 3D.
