Autodesk FBX is a proprietary 3D geometry exchange format with a freely available SDK. It has recently gained popularity again as the main exchange format for the Unreal and Unity game engines and related AR/VR applications. It is currently lacking in terms of modern material support (e.g. PBR) and metadata transport, but efforts are underway by Autodesk to improve this. For non-AR/VR use cases, we recommend glTF instead.
