## About cl-fbx
This is a wrapper library around "ufbx"(https://github.com/ufbx/ufbx), a C library for parsing the FBX 3D model file format. As the library and structures involved are quite large, please refer to the C library for more detailed documentation on the individual structures, functions, and fields.
## How To
First, load the library, and then parse a file:
:: common lisp
(org.shirakumo.fraf.fbx:with-file (file #p"my-model.fbx")
(describe file))
::
Files can be loaded from a file on disk, an octet stream, an octet vector, or a direct memory pointer.
When you are done with the file, you must ``free`` it to clear out any foreign memory resources taken up by it. Other calls may also return fresh instances that must be manually freed as appropriate. For most cases, using ``with-freeing`` should help to ensure data does not get retained more than necessary.
All structures returned by the library are wrapped in ``wrapper`` instances, which are thin instances that give more convenient Lisp-side access to the data. For lists, a ``foreign-vector`` is returned, which can be indexed with the standard sequence functions on implementations supporting the extensible-sequences protocol.
You can at any time also invoke ``describe`` on an instance to get a listing of all the slots and their contents. This should make it much easier to traverse the data.
