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).
- Format Alert: CityJSON and GeoJSON both use the .json extension - always verify the data structure before processing.

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!
3D Studio File
A widely recognized format used for storing 3D polygonal mesh models, originally developed for Autodesk 3D Studio. Known for its broad compatibility and straightforward structure, it remains a popular choice for real-time visualization, gaming, architectural modeling, and lighting design despite its legacy limitations.
Key Features & Capabilities
- Extensive Support: The 3DS format supports model naming conventions, reusable geometry instances, and material definitions including transparent colors and texture mapping. Its hierarchical structure preserves object relationships and basic animation data.
- High Compatibility: 3DS files work with most major 3D software including DIALux for lighting design, Blender, Cinema 4D, and game engines like Unity. This makes it ideal for cross-platform asset sharing.
- Technical Limitations: Due to its DOS-era origins, the format has strict constraints: mesh names are limited to 8 characters, and each mesh object can contain no more than 32,767 triangles. The format also lacks support for modern features like PBR materials or NURBS surfaces.
3DS File Converters
Our Autoconverter and Automesher Application automatically resolve legacy 3DS format constraints by intelligently partitioning large models into compliant, optimized sub-meshes. This ensures your 3D assets maintain integrity when exported to the 3DS format. While newer formats offer more features, 3DS remains valuable for legacy systems, lighting simulations, and situations requiring broad software support without complex dependencies.
