The FBX file format, short for Filmbox, is a proprietary file format developed by Autodesk. It's primarily used for exchanging 3D data between different 3D applications. This includes models, animations, skeletons, scenes, and other related data. FBX is designed to be interoperable, allowing artists and developers to move assets seamlessly between software packages like Maya, 3ds Max, MotionBuilder, Unity, and Unreal Engine. It supports a wide range of features, including geometry, textures, materials, lights, cameras, and animation rigs. The format handles both static and dynamic data, making it suitable for game development, film production, architectural visualization, and other 3D-related fields. FBX files can store data in either binary or ASCII format, with binary being more compact and ASCII being more human-readable (though larger in size). The format also supports embedded media, meaning textures and other external files can be included within the FBX file itself, simplifying asset management. FBX has become a widely adopted standard for 3D data exchange due to its comprehensive feature set and broad software support.
