What is an OBJ File? (Alias Wavefront Object Explained)
The OBJ file format is a widely used open standard for storing and exchanging 3D geometry, originally developed by Wavefront Technologies. Unlike binary formats, OBJ files use a human-readable text format, making them highly compatible across 3D modeling, animation, and rendering software.
Key Features and Benefits of OBJ Files
- Multiple Named Objects: OBJ files can contain multiple 3D objects within a single file, each organized with individual names, ideal for complex 3D scenes and asset management.
- Surface Materials and Textures: OBJ files support detailed surface definitions, including transparent materials and texture mapping, enabling realistic 3D model rendering.
- Quad and Triangle Support: Geometry in OBJ files can include both quads and triangles. During OBJ file conversion, quads are automatically divided into triangles to ensure compatibility with applications that only support triangular meshes.
- File Size Considerations: As a text-based format, OBJ files tend to be larger than binary formats like SKP or 3DS, which can impact loading speeds and storage requirements for complex models.
Convert OBJ Files Easily with Autoconverter
Need a reliable OBJ file converter? Our Autoconverter software offers high-accuracy, lossless conversions between OBJ and other popular 3D formats like STEP, STL, and SKP. With fast processing, advanced optimization, and an intuitive interface, it's the ideal tool for professional 3D model conversion.
For AutoCAD users, our Automesher Application enables direct import and export of OBJ files within your CAD environment, ensuring seamless integration with your workflow.
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.
