GLTF is a file format for storing 3D scenes and models, the structure of which is written in the JSON standard. This format compresses three-dimensional scenes well and minimizes processing during the execution of applications using WebGL and other APIs. A binary version of this format is also available, which is called GLB, the only difference of which is that everything is stored in a single file with the GLB extension.
All export parameters of the *.gltf format are similar to the parameters described in the X3D, IV, VRML 2.0, TF3D, PLY, OBJ Formats section.
All export parameters of the *.glb format are similar to the parameters described in the Parasolid Formats section.
