Caligari TrueSpace COB File Format
The COB file format was developed by Caligari Corporation for its 3D modeling and animation software, TrueSpace. COB files store complete 3D scene data including geometry, materials, textures, lights, and animation. Though TrueSpace is now discontinued, COB remains an essential format for preserving and converting legacy 3D content.
Key Features of COB Files
- Full 3D Scene Storage: COB files encapsulate entire scenes with objects, lighting, cameras, and animation data.
- Two Format Variants:
- ASCII COB: Human-readable format ideal for manual inspection and debugging.
- Binary COB: Compact format optimized for performance and faster loading times.
- Material & Texture Support: Includes surface colors, image textures, and basic shading information.
- Geometry Types: Supports both NURBS-based and polygon mesh 3D models for greater flexibility.
COB File Conversion Tools
Use Autoconverter and Automesher Application to import and convert COB files into modern 3D formats such as FBX, OBJ, SKP, STEP, and SAT. Our converters retain crucial data including UV mapping, materials, and mesh topology by utilizing the Open Asset Import Library (Assimp) for accurate and reliable file processing.
Note: COB files can only be imported - exporting to COB format is not supported.
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.
