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!

OBJ Alias Wavefront Object File

A text-based file format, open standard for storing and exchanging 3D geometry data, widely used across 3D modeling, animation, and rendering software. Unlike binary formats, OBJ files store mesh data in human-readable text, making them highly compatible but less storage-efficient.

Main Benefits and Features

  • Named Group Objects:

    OBJ files can store multiple objects with different names in a single file, which can be useful for organizing complex 3D scenes.

  • Surface Materials:

    The OBJ file format supports surface materials with transparent colors and texture images, providing more realistic and detailed 3D models.

  • Geometry Primitives:

    OBJ files can store geometry primitives in the form of quads or triangles. However, during the OBJ file conversion using our converters, any quad primitives will be simplified into two triangles, as only triangular facets are supported.

  • OBJ File Size:

    Due to its textual format, OBJ files tend to have larger sizes compared to binary file formats like 3DS (3D Studio) or SKP (SketchUp). This means that OBJ files may take longer to load or transfer, and may require more storage space.

OBJ File Conversion

Autoconverter is the best OBJ file converter due to its high accuracy, fast processing speed, and wide 3D format support. It ensures lossless conversions while preserving model details, offering a user-friendly interface for seamless file conversion. If you need to handle OBJ files in AutoCAD, you can use our Automesher Application, which allows for seamless import and export of OBJ files directly in your CAD environment.
