USD & USDZ File Format - Universal Scene Description by Pixar
Universal Scene Description (USD), developed by Pixar, is a powerful framework for creating, editing, and exchanging complex 3D scenes. Now widely adopted in the VFX, animation, and AR industries, the USD ecosystem supports large-scale pipelines through its modular, scalable, and cross-platform architecture. USDZ is its optimized variant for mobile AR applications, especially on Apple devices.
Key Features of USD and USDZ
- Modular and Composable Architecture: USD enables efficient scene composition by referencing multiple files, allowing teams to collaborate on complex projects without data duplication or conflicts.
- Cross-Platform Interoperability: USD ensures accurate data exchange across software platforms like Maya, Blender, Unreal Engine, and more - ideal for collaborative, multi-tool workflows.
- Hierarchical and Layered Scene Representation: Easily organize 3D data using namespaces, variants, layers, and references, providing unparalleled control over versioning and detail management.
Convert USD, USDA, USDC, and USDZ Files
Our Autoconverter and Automesher Application software supports full-featured conversion for USD, USDA, USDC, and USDZ formats. Powered by the OpenUSD framework, our tools allow you to import, export, and convert USD files to popular 3D formats like GLTF, FBX, STL, OBJ, SKP, and STEP. Whether you are developing for AR, animation, or CAD pipelines, our converters offer precision and compatibility across platforms.

CityJSON (3D City Model) 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.
