Updates to the C3D.ORG site

February 22, 2010

Added a page describing a user-written LabVIEW interface that documents using the C3Dserver within the National Instruments LabVIEW environment to access C3D files.

October 12, 2009

Added sample31.zip, a very large dataset with two C3D files that contain 3D point and analog data. These are interesting because each C3D file contains more than 65534 frames of data and, as a result, these files can only be opened by applications that support the use of the TRIAL group to store frame numbers within the parameter block.

September 22, 2009

Added Northern Digital to the list of companies supporting C3D files as the software supplied with their motion capture systems exports data in C3D format and can stream C3D in real time.

August 30, 2009

Added a link to an application called BTK. BTK is an open-source and cross-platform library for biomechanical analysis that can read and write C3D, TRC, and ANC data files.

23 July 2009

Added three sample C3D files supplied by Biogesta. These files are stored in sample30.zip on the FTP site.

2 July 2009

Added Visol and Kwon3D to the list of companies supporting C3D files.

19 June 2009

Added Biogesta to the list of companies supporting C3D files after Pascal Cloup wrote to say that their software supports the import and export of C3D files.

21 May 2009

Added NaturalPoint to the list of vendors supporting C3D files. Sample C3D files are posted in sample29.zip on the FTP site.

Removed the links to the user-written stand-alone MATLAB driver that read C3D point and analog data from simple C3D files into three dimensional data arrays that can be accessed by MATLAB because the drive is not maintained - the driver files are still available here. This driver is largely superceded by the C3Dserver.

23 April 2009

Indexed the site contents and add a PHP server based search facility to the right side panel. Spent most of the day debugging CSS. The panel layout has changed to accomodate the search box with the public domain statement now on the lower left panel.

13 April 2009

Added this update page to document changes to the information contained in the C3D site.

7 April 2009

Added AnyBody Technology to the list of companies supporting C3D files. The AnyBody Modeling System reads C3D files but does not create them. Prior to the creation of this page we updated the appearance of the web site and added several new sample C3D files to site.
