About FBX binary file format

I want to read FBX binary format, but I want to not use FBX sdk of Autodesk.

Please teach when someone knows that w开发者_Python百科eb sites of fbx binary file format.

According to Wikipedia - http://en.wikipedia.org/wiki/FBX - Blender includes a Python script for export to FBX format. This is probably the closest thing you'll find for documentation of it. Sounds like a painful task of RTFS.

Currently the FBX binary format is undocumented.

At the moment I'm working on a loader though based on work by assimp, Both parsers are roughly equivalent.

https://github.com/assimp/assimp / https://github.com/assimp/assimp/blob/master/code/FBXBinaryTokenizer.cpp

I wrote pyfbx which is a standalone Python3 port of the C++ library which is apart of assimp and includes an example tool fbx2json.

Note that these only parse the data, giving you something like XML/JSON (a tree typed data), but you still need to make sense of this. I managed to get a mesh importer working in couple of hours, but if you want materials, animation etc, this is more work.
