Sample C3D data files

This collection of files is a resource for programmers, developers and users who want to test their software applications for compatibility with the C3D standard. Each downloadable zip file contains a text file with additional information - the most recent additions to this collection are at the bottom of the page.

All software applications that claim C3D compatibility must be able to open and read the sample files that meet both the Original and Current C3D specifications as well as handle C3D files that contain errors in a sensible manner.
