about python version

[honda6]

hi, is your library written in python3.6? and how can i install fbx sdk in python3.6?

Hi, python 3.6 is only required to use pygltflib. The other code should also work with python 3.5, if you disable the import of that library in vis_utils/io/init.py line 32.

We have also implemented a custom cython wrapper to import character models using the C++ FBX SDK that can be compiled to run with other python versions. If it would help, we can upload it to another repository.

Thank you for your reply. The fbx sdk is very useful, and i'm looking forward to you uploading it, it will help me a lot, thanks~

Hi I have uploaded now a first version of the FBX SDK wrapper to the following repository:
https://github.com/eherr/py_fbx_wrapper

It was only tested with files from MakeHuman that contain a character with a skeleton and will not work with most files.

Thanks a lot~

You are welcome

Hi I have uploaded now a first version of the FBX SDK wrapper to the following repository:

It works well~By the way,It seems need to add "libxml2-md.lib;zlib-md.lib;" in for building.
However, is there any fbx export SDK wrapper, for handling mesh animation.

Thanks for noticing the missing libs. I will update the project file.

Yes I have tested importing the animation using the official Python SDK and also had some code using the C++ SDK. The latter is, however, not yet integrated with the custom wrapper.

I will look for it and, if I find it, add it to the repository or alternatively post it as a gist.

Hi, you can find the animation importer code for the Python FBX SDK here: https://gist.github.com/eherr/ead35014d579a97754351482b807eca5

It should be possible to export an animation to BVH using this code and anim_utils:

import fbx_importer
from anim_utils.skeleton_builder import SkeletonBuilder
from anim_utils.motion_vector import MotionVector

fbx_skel, fbx_anims = fbx_importer.load_fbx_file(filename)
skel = SkeletonBuilder().load_from_fbx_data(fbx_skel)
mv = MotionVector()
mv.from_fbx_data(fbx_anims["name"])
mv.export(skel, out_filename)

I will try to add support for animations to the custom FBX SDK wrapper.

I have uploaded now a first version of the custom FBX SDK Wrapper that also returns the animation curves which can be used as follows:

import fbx_importer

data = fbx_importer.load_fbx_file(filename)

Data contains a "skeleton", "animations" and a "mesh_list". Each entry of the mesh list contains with vertices, normals, uvs, bone ids and weights. Each animation contains the "frame_time" and a "curves" dict that stores the joint names as keys and a list of frames with "local_translation" and "local_rotation" as keys.
