Software:Visual3D
Visual3D is a proprietary general purpose biomechanics modeling and analysis software package developed and published by C-Motion, Inc. The software makes use of the C3D file format for input data as well as real-time motion data streamed by several hardware manufacturers. The program is not restricted in terms of marker sets and provides a historical audit trail of data changes. Modeling features include kinematics, inverse dynamics (kinetics) and inverse kinematics (global optimizations).
Visual3D evolved from a clinical research tool for 6DoF modeling developed at the NIH by Tom Kepple (originally called "Move3D").
Visual3D is a toolbox of publicly available analysis and signal processing algorithms and methods which are documented in the textbook Research Methods in Biomechanics from Human Kinetics, and also on the Visual3D wiki pages.
Visual3D is used by academics, clinicians, sports analysts and others interested in understanding biological motion. For an example of gait analysis, this video.
