free fbx files
Free fbx file are FBX (Filmbox) is a proprietary file format (.fbx) developed by Kaydara and owned by Autodesk since 2006. It is used to provide interoperability between digital content creation applications. FBX is also part of Autodesk Gameware, a series of video game middleware.
FBX originated as a replacement file format for Canadian company Kaydara’s Filmbox, a software for recording data from motion capture devices. Prior to 1996, Filmbox 1.0 used a file format called FLM. The format only supported motion data, user preferences and a list of devices used in the capturing of the motion data. This data was a serialized version of the libraries (binary dump), containing read/write memory data. This method of storing data did not work well with different versions of Filmbox. There was also demand from early adopters of Filmbox to implement a target character in a scene with the motion capture data, to enable the visualization of the data in a 3D view with display markers.
