This is a small library for reading and writing C3D binary files. C3D files are a standard format for recording 3-dimensional time sequence data, especially data recorded by a 3D motion tracking apparatus.

Build and install using the normal Python distutils goodness

python setup.py build
python setup.py install

If you just want to use the library, install with pip

pip install lmj.c3d

This package includes a basic test for the library (c3d_test.py) and an OpenGL-based visualization tool for watching C3D files (c3d_viewer.py).

This library is minimally effective, in the sense that the only motion tracking system I have access to (for testing) is a Phasespace system. If you try out the library and find that it doesn't work with your motion tracking system, let me know.

Also, if you're looking for more functionality than just reading and writing C3D files, there are a lot of better toolkits out there that support a lot more file formats and provide more functionality. The biomechanical toolkit is a good example.
