The 3D Biomechanics Data Standard

This web site provides definitive information about the C3D file format for programmers, manufacturers and end-users. The C3D format is a public domain, binary file format that has been used in Biomechanics, Animation and Gait Analysis laboratories to record synchronized 3D and analog data since the mid 1980's.  It is supported by all 3D major Motion Capture System manufacturers, as well as other companies in the Biomechanics, Motion Capture and Animation Industries.
