Convert GLTF to JSON: The Key References

GLTF to JSON: Resources

Provided below is a curated list of supplementary resources focusing on the interoperability and exchange between GLTF and JSON files. Leverage these to streamline the GLTF to JSON files conversion.


GLTF File GLB

GLTF (Graphics Language Transmission Format) is a file format developed and maintained by the Khronos Group organization. There are currently two versions of the GLTF file format available: the original 1.0 and the more recent 2.0, with the latter being preferred due to its newer features. By default, a GLTF file is saved in ASCII text mode. However, to save a GLTF file with all referenced texture images in binary mode, the GLB file extension should be used. Our GLTF and GLB conversion tools, Autoconverter and Automesher Application, offer full support for importing and exporting both GLTF and GLB files, thanks to the open asset import library.


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.
