OBJ to JSON Conversion

This list provides valuable resources, filled with step-by-step guides and expert advice for converting OBJ files to JSON format using our converters. Review them now to ease your OBJ files conversion later.


OBJ Alias Wavefront Object File

A text-based file format that is extensively used for 3D geometry objects across a variety of 3D software programs. Some of the benefits and features of OBJ files are:

  • Named Group Objects: OBJ files can store multiple objects with different names in a single file, which can be useful for organizing complex 3D scenes.
  • Surface Materials: The OBJ file format supports surface materials with transparent colors and texture images, providing more realistic and detailed 3D models.
  • Geometry Primitives: OBJ files can store geometry primitives in the form of quads or triangles. However, during the OBJ file conversion using our Autoconverter software, any quad primitives will be simplified into two triangles, as only triangular facets are supported.
  • OBJ File Size: Due to its textual format, OBJ files tend to have larger sizes compared to binary file formats like 3DS (3D Studio) or SKP (SketchUp). This means that OBJ files may take longer to load or transfer, and may require more storage space.

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.
