What is a .c3d file?
File Extension Details
The C3D (Coordinate 3D) file format is a public domain, binary file format used extensively in the fields of biomechanics, motion capture, and gait analysis. Originally developed in the 1980s, it has become the global standard for storing 3D coordinate data, analog data such as electromyography (EMG) or force plate signals, and associated metadata in a single, synchronized file. The format is designed to be platform-independent and supports various data types, including floating-point and integer representations, which allows it to maintain high precision for clinical research and sports science applications. Its architecture consists of a header section, a parameter section for metadata like labels and sampling rates, and a data section for the actual 3D coordinates and analog samples. Because it is an open standard, it is supported by almost all major motion capture hardware manufacturers and analysis software packages, ensuring that researchers can share and process movement data across different systems without losing critical synchronization or descriptive information.
