JSON to U3D
Please find below the list of our other useful resources related to JSON and U3D interoperability and exchange that could help you with the JSON to U3D conversion.
JSON CityJSON File
JSON (CityJSON) file format is an optimized version of CityGML OGC (Open Geospatial Consortium) standard file format for storing and exchanging 3D city models and landscapes. The CityJSON file format supports city objects names, objects nested hierarchy, and custom materials with texture images. The Autoconverter software, our CityJSON file converter, allows you to read and write CityJSON JSON geometries with the custom attributes and convert between other common 3D mesh file formats.
U3D File
U3D (Universal 3D) is an open source compressed file format initiated by the 3D Industry Forum to store three dimensional triangular meshes with the additional properties e.g. color, transparency or texture coordinates for the general 3D graphics industry. The U3D file format is mostly used in combination with the 3D PDF technology which allows you to generate PDF documents containing interactive 3D data from the U3D files. Autoconverter and Automesher Application, our U3D file converters can read and write to and from U3D file format thanks to the publicly available open source IFX converter library provided by the Intel company. To simplify generation of 3D PDF documents our converters create a common TEX script which can be easily used to generate a PDF document with the standard and free LaTeX software.
