What is C3D.ORG?
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 is used in Biomechanics, Animation and Gait Analysis laboratories to record synchronized 3D and analog data. It is supported by almost all 3D Motion Capture System manufacturers, as well as other companies in the Biomechanics, Motion Capture and Animation Industries.
Within this site you will find:
- Complete information about the C3D file format via an on-line manual.
- Detailed C3D file format specifications and design overview.
- Free C3D software tools and documentation.
- Links to companies with software programs that access C3D files.
- Sample C3D data files that can be downloaded for testing.
- A downloadable PDF User Manual that can be printed and redistributed.
- The C3Dserver - a free Software Development Kit for C3D files.
- A suite of "known good" C3D files for software development and testing.
The web site is designed to be easy to access, with a minimum of graphics, so that each page loads quickly. Most pages will load in less than ten seconds over a 28.8k modem connection.
Although maintained by Motion Lab Systems, the information provided on these web pages is not intended to push a visitor towards any specific hardware or software supplier. The only criteria for information on this site is that it is associated with the C3D format. We welcome comments and program submissions from all C3D users, equipment manufacturers and application vendors.
Please note that the structure of the C3D web site has changed significantly as the complete C3D User Manual is now available on-line as well as a printable Adobe PDF file. If you link to this site we recommend that you link to this main index page as internal links may change.
