OFF Object File Format

A straightforward, human-readable file format designed for representing 3D polygonal models. As a lightweight alternative to complex CAD formats, OFF focuses on storing essential geometric data - vertices, edges, and faces - without proprietary constraints.

Key Features of OFF

  • ASCII Text Files:

    : OFF files are text-based and use a simple syntax to store geometric data of 3D objects. The files can be easily edited and viewed with any text editor or viewer.

  • Polygonal Shapes:

    The OFF format allows to store 3D triangles, quads, and other generic polygonal shapes. Each shape is defined by a list of vertices and a list of faces.

  • Limitations:

    OFF files support only geometric data - materials, textures, and group names from source files are discarded during conversion.

OFF File Conversion

Our software offers two specialized approaches for OFF file conversion. Autoconverter handles conversion of OFF files to common mesh formats including STL, SKP, OBJ, and PLY, maintaining the original polygonal structure. Autoshaper provides advanced conversion of OFF polygonal data into smooth NURBS surfaces, exporting to BREP, STEP, and IGES formats for CAD workflows.

JSON CityJSON File

A modern, JSON based (JavaScript Object Notation) file format designed for storing 3D city models. It efficiently represents buildings, roads, bridges, and other urban features with support for textures, semantics, and metadata.

Key Features of CityJSON

  • JSON-Based:

    Lightweight, human-readable, and easy to parse (no complex XML like CityGML).

  • Semantic Richness:

    Preserves object attributes (e.g., building heights, roof types, road classifications).

  • LOD Support:

    Stores multiple Levels of Detail (LOD1 - LOD4) for flexible use cases.

  • Web-Ready:

    Works seamlessly with JavaScript, APIs, and 3D web viewers (like Cesium or Three.js).

  • Open Standard:

    Developed and maintained by the 3D Geoinformation Group (Delft University).

CityJSON File Conversion

Autoconverter and Automesher Application let you import, export, and convert CityJSON files to formats like STL, OBJ, SKP, and 3DS while preserving semantic data and geometries. Easily integrate 3D city models into your workflows - try our CityJSON converters today!
