JSON to OFF Conversion

We’ve gathered a list of valuable resources, featuring comprehensive guides and expert advice for converting JSON files to OFF format using our converters. Study them now to make your JSON files conversion easier later.


JSON CityJSON File

A file format for the efficient storage and exchange of 3D city models and landscapes. It has the following benefits and features:

  • Optimized CityGML: The CityJSON format is based on CityGML, which is an OGC standard for representing and exchanging 3D urban data. However, CityJSON is optimized for simplicity and efficiency, using JSON instead of XML as the underlying syntax. CityJSON reduces the file size and complexity of CityGML files, making them easier to process and manipulate.
  • 3D City Data: The CityJSON files can store 3D city models and landscapes, which are composed of various city objects, such as buildings, roads, bridges, vegetation, etc. Each city object has a name, a geometry, and a set of attributes. The format also supports nested hierarchy, reusable geometry component instances, and custom materials with texture images, which enhance the realism and detail of the 3D city data.
  • CityJSON Converter: Autoconverter allows you to import and export CityJSON files, and convert them into various other 3D mesh file formats, such as STL, OBJ, SKP, 3DS`, etc. Our software supports the reading and writing of CityJSON geometries with custom attributes, which preserve the semantic information of the 3D city data.

OFF Object File Format

A simple and flexible file format for 3D polygonal objects. It is a versatile tool for storing and transferring 3D geometric data. It has the following features:

  • ASCII Text Files: : The 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 files can store 3D triangles, quads, and other generic polygonal shapes. Each shape is defined by a list of vertices and a list of faces.
  • OFF Converters: Autoconverter is our primary OFF file converter that can convert OFF files into other mesh file formats, such as STL, SKP, OBJ, PLY, etc. Autoshaper is another OFF file converter that can convert OFF files into smooth NURBS shapes, and save them into BREP, STEP, IGES, etc.
  • Limitations: The OFF files do not support the conversion of materials, textures, or group names from more sophisticated 3D file formats. These attributes are not stored in the OFF files and are lost during the conversion process.
