GLB Graphics Language Transmission File

A file format developed and maintained by the Khronos Group organization. It is designed to facilitate the efficient storage and exchange of 3D models. It has the following features:

  • Khronos Group: Khronos Group is a consortium of industry leaders that creates open standards for graphics, media, and parallel computing. This organization developed the GLTF file format.
  • GLTF Versions: There are two versions of the GLTF file format that are available:
    • GLTF 1.0: Supports basic geometry, simple materials with textures, basic skeletal animations with joint hierarchies, scenes with a single root node and a hierarchy of child nodes, etc.
    • GLTF 2.0: Supports more features, such as PBR (Physically Based Rendering) materials, Draco compression, advanced skeletal animations, skinning, morph targets, etc.
  • ASCII and Binary Modes: By default, a GLTF file is saved in ASCII text mode, which is human-readable and easy to edit. To save a GLTF file with all referenced texture images in binary mode, the GLB file extension should be used. This reduces the file size and the number of files.
  • GLTF Converters: Autoconverter and Automesher Application allow you to import and export GLTF and GLB files, and convert them into various other 3D file formats. Our products also support the use of Draco compression, which can significantly reduce the size of GLTF and GLB files without compromising visual fidelity.

JSON CityJSON File

A file format for the efficient storage and exchange of 3D city models and landscapes. It has the following benefits and features:

  • Optimized CityGML: The CityJSON format is based on CityGML, which is an OGC standard for representing and exchanging 3D urban data. However, CityJSON is optimized for simplicity and efficiency, using JSON instead of XML as the underlying syntax. CityJSON reduces the file size and complexity of CityGML files, making them easier to process and manipulate.
  • 3D City Data: The CityJSON files can store 3D city models and landscapes, which are composed of various city objects, such as buildings, roads, bridges, vegetation, etc. Each city object has a name, a geometry, and a set of attributes. The format also supports nested hierarchy, reusable geometry component instances, and custom materials with texture images, which enhance the realism and detail of the 3D city data.
  • CityJSON Converter: Autoconverter allows you to import and export CityJSON files, and convert them into various other 3D mesh file formats, such as STL, OBJ, SKP, 3DS`, etc. Our software supports the reading and writing of CityJSON geometries with custom attributes, which preserve the semantic information of the 3D city data.
