This library was originally written by Martin Felis for the the inverse kinematics program puppeteer. It was never published seperatly and had some issues.
C3DFile is a simple library to access motion capture data that is stored in C3D files. One can retrieve the marker position at individual frames and also query values from the C3D header and also parameter values.
Oh, and it also comes with a wrapper for GNU Octave.
For usage see either in the tests file at tests/c3dfiletests.cc or the source code of the c3dexport utility at src/c3dexport.cc
The library is published under the MIT license. Here is the full license text:
