Extract text from 3D motion capture files (C3D)
To convert C3D motion capture files to another format, you need Visual3D or other 3D software.
To convert other file formats to the "Biomechanics Motion Capture" file type, you need software like Visual3D or a similar tool.
The .C3D file format is most commonly used as the public domain Biomechanics Standard for 3D motion capture data. It stores both 3D coordinate trajectories and analog data (such as force plate or EMG readings) in a synchronized binary structure. Other software also uses the .C3D extension for completely different purposes, including medical imaging data by Ziehm Imaging, flight simulator models in Condor Soaring Simulator, architectural projects in Cadvilla, and 3D animations in Corel MotionStudio 3D.
Opening or editing a .C3D file requires highly specialized software. Biomechanics files are typically handled by tools like Visual3D or the open-source Mokka viewer. The major disadvantage of this format is its niche nature. Native operating systems cannot preview these files, and standard web browsers do not support them. Additionally, because the extension is shared across fundamentally different industries (biomechanics, architecture, gaming), users often struggle to find the right application to open their specific file.
Users typically need to convert biomechanics .C3D files to CSV or TXT for raw numerical analysis in Excel, MATLAB, or Python. For 3D animation and game development, converting the motion data to FBX or BVH is preferred. If the file is an architectural or CAD model, target formats like OBJ, STEP, or STL are ideal. Be aware that converting to text formats like CSV strips away the structured 3D playback and leaves only massive tables of raw data.
.C3D files are difficult to convert because the exact binary structure depends entirely on which software created them. Standard online converters fail because they cannot guess if the file contains a human motion capture sequence, a medical scan, or an architectural CAD model. Often, only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format (like GZIP or Microsoft Compound), viewing or conversion may still be possible.
Convert.Guru analyzes your C3D file, detects the exact format, and lets you read the text inside.
Users also converted C3B, C4D, FBX, STL, AAB, GLB, TRC, ZIP, G3D, JPG, PDF, XAPK and CRDOWNLOAD files.
If you want to convert C3D file to CSV, FBX, TRC, BVH, OBJ, DAE, 3DS, MAX, BLEND, MA, MB or C4D, you can use Visual3D or similar software from the "3D Motion Capture Data" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to C3D, try Visual3D or another comparable tool in the "3D Motion Capture Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our C3D converter.
