JSON CityJSON File

A modern, JSON based (JavaScript Object Notation) file format designed for storing 3D city models. It efficiently represents buildings, roads, bridges, and other urban features with support for textures, semantics, and metadata.

Key Features of CityJSON

  • JSON-Based:

    Lightweight, human-readable, and easy to parse (no complex XML like CityGML).

  • Semantic Richness:

    Preserves object attributes (e.g., building heights, roof types, road classifications).

  • LOD Support:

    Stores multiple Levels of Detail (LOD1 - LOD4) for flexible use cases.

  • Web-Ready:

    Works seamlessly with JavaScript, APIs, and 3D web viewers (like Cesium or Three.js).

  • Open Standard:

    Developed and maintained by the 3D Geoinformation Group (Delft University).

CityJSON File Conversion

Autoconverter and Automesher Application let you import, export, and convert CityJSON files to formats like STL, OBJ, SKP, and 3DS while preserving semantic data and geometries. Easily integrate 3D city models into your workflows - try our CityJSON converters today!

GLB Graphics Language Transmission File

A file format developed and maintained by the Khronos Group organization, a consortium of industry leaders that creates open standards for graphics, media, and parallel computing. It is designed to facilitate the efficient storage and exchange of 3D models.

Key Features of GLTF and GLB

  • 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.

  • Embedded Textures:

    GLTF/GLB files allow for a more streamlined and efficient way to manage 3D assets. By storing textures directly within the file, these formats eliminate the need for separate image files, making the 3D model self-contained and easier to distribute.

GLTF/GLB File Conversion

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.
