Convert U3D to JSON: All You Need to Know

U3D to JSON: Resources

Listed below are additional resources pertaining to the interoperability and exchange of U3D and JSON file sources. These will be valuable in guiding you through the U3D to JSON files conversion.


U3D File U3D

The U3D (Universal 3D) file format is an open-source compressed format, initiated by the 3D Industry Forum. It’s designed to store three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates. This format plays a significant role in the general 3D graphics industry, particularly in conjunction with 3D PDF technology. It enables the generation of PDF documents containing interactive 3D data from U3D files. Both of our U3D file converters, Autoconverter and Automesher Application, are capable of reading and writing to and from the U3D file format. This is made possible thanks to the publicly available open-source IFX conversion library provided by Intel. To streamline the process of generating 3D PDF documents, our converters create a standard TEX script that can be easily utilized with free LaTeX software.


CityJSON File JSO

JSON (CityJSON) is an optimized version of the CityGML OGC (Open Geospatial Consortium) file format, designed for the efficient storage and exchange of 3D city models and landscapes. The CityJSON file format supports city object names, nested hierarchy, reusable geometry component instances, and custom materials with texture images. Our Autoconverter JSON file converter facilitates seamless reading and writing of CityJSON JSON geometries with custom attributes. It also allows for smooth conversion between other common 3D mesh file formats.
