JSON 3D City Model (CityJSON) File

The CityJSON file format is a modern, JSON-based (JavaScript Object Notation) standard designed for storing and exchanging 3D city models. It efficiently encodes buildings, roads, bridges, urban furniture, and other city objects, offering strong support for textures, semantics, and detailed metadata. CityJSON is a lightweight alternative to CityGML, optimized for simplicity, web integration, and high-performance applications.

Key Features of CityJSON Files

  • JSON Simplicity: CityJSON files are lightweight, human-readable, and easily parsed by common programming languages, avoiding the complexity of XML structures like in CityGML.
  • Semantic Data: Preserves rich metadata, including building heights, roof shapes, material classifications, and road types, enhancing 3D GIS and urban analysis.
  • LOD (Level of Detail) Support: Manages multiple levels of detail (LOD1 through LOD4) to suit diverse visualization, simulation, and analysis needs.
  • Web-Friendly Format: Perfect for 3D web visualization and integration with JavaScript libraries like Cesium and Three.js.
  • Open and Extensible: Developed by the 3D Geoinformation Group (Delft University of Technology), CityJSON is an open standard that promotes interoperability and innovation.
  • File Extension Note: Both CityJSON and GeoJSON use the .json extension - ensure you verify the file structure before processing to avoid errors.

CityJSON File Conversion Made Easy

With Autoconverter and Automesher Application, you can seamlessly import, export, and convert CityJSON files into formats like STL, OBJ, SKP (SketchUp), and 3DS. Our tools preserve geometric precision and semantic information, making it easy to integrate 3D city models into your CAD, GIS, and 3D visualization workflows.

IV IV File - Open Inventor 3D Scene Format

The IV file format, also known as the Open Inventor format, is a text-based 3D graphics standard originally developed by Silicon Graphics (SGI). Designed for complete 3D scene representation, IV files use hierarchical scene graphs to define geometry, lighting, materials, and textures. The format played a key role in early 3D development and is tightly integrated with the Open Inventor API - an object-oriented C++ toolkit used in scientific visualization, CAD, and simulation.

Key Features of IV Files

  • Readable File Structure: Human-friendly ASCII format that organizes 3D content using nested nodes for easier editing and scripting.
  • Scene Graph Hierarchy: Defines parent-child relationships between 3D objects using a directed acyclic graph (DAG) structure.
  • Rich Visual Metadata: Includes lighting, shading, camera settings, and full material definitions (specular, ambient, diffuse, transparency).
  • Texture Support: Handles both procedural and raster-based textures using UV mapping coordinates.
  • Legacy Compatibility: Ideal for scientific and engineering applications that still rely on Open Inventor-based platforms.

Convert IV Files to FBX, glTF, OBJ, and More

Use Autoconverter to easily convert IV files to modern 3D formats like FBX, glTF, STL, OBJ, and DAE. Our IV file converter preserves full scene structure, materials, and geometry, bridging the gap between legacy and modern 3D workflows. Whether you are updating legacy data or working in cross-platform 3D environments, Autoconverter makes IV file conversion seamless and reliable.
