How to Convert JSON to X3D?

Ready to convert JSON to X3D? Follow this practical step-by-step guide and get it done with our powerful conversion tool:

  1. 📥 Download and Install

    Download and install Autoconverter on your system. This application will let you to convert your JSON files to X3D format - no additional CAD software required.

  2. 📂 Open Your JSON File

    Go to File > Open to load your JSON file (*.json, *.cityjson), or drag and drop it directly into the application window. The model loads into the 3D viewport for inspection before converting.

  3. 💾 Save As X3D Format

    Go to File > Save As, select X3D (*.x3d, *.x3db) as the output format, choose your destination folder and filename, then click Save to complete the JSON to X3D conversion.

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.

X3D X3D File - Extensible 3D Graphics Format

X3D (Extensible 3D) is an open-standard, royalty-free 3D file format developed by the Web3D Consortium. Based on XML, X3D is designed for real-time 3D rendering and interactive scenes directly within web environments. It is the official successor to VRML and supports animations, shading, interactivity, and integration with modern web technologies like HTML5 and WebGL.

Key Features of X3D and X3DB Files

  • VRML Successor: X3D offers backward compatibility with VRML while expanding functionality with modern web capabilities.
  • Web-Ready Format: Seamlessly integrates with X3DOM, Three.js, and other HTML5/JavaScript libraries for interactive 3D graphics on the web.
  • Scene Graph Structure: Organizes 3D content hierarchically, allowing precise control over transformations, lighting, geometry, and animations.
  • Text-Based XML Encoding: Human-readable file structure makes it easy to edit, validate, and manage X3D content in development workflows.

Convert X3D Files to Other 3D Formats

Our Autoconverter and Automesher Application provide powerful tools to convert X3D and X3DB files into popular 3D formats including STL, OBJ, 3DS, SKP, and STEP. Maintain full scene integrity, geometry, and materials while transitioning between web-based and CAD-ready formats.
