glTF (short form of Graphics Language Transmission Format or GL Transmission Format) is a standard file format for three-dimensional scenes and models. A glTF file uses one of two possible file extensions: .gltf (JSON/ASCII) or .glb (binary). Both .gltf and .glb files may reference external binary and texture resources.
The VividWorks 3D Configurator utilizes glTF 2.0 Separate file format where the data is split into multiple files. .gltf (json/ASCII) file containing metadata in JSON format and .bin file containing the polygon mesh data.
Additionally the 3d model related materials may be incorporated and referenced by the model in the .gltf file. The glTF files are uploaded in a .zip package into the configurator.
