FreeMoCap vs visage|SDK

FreeMoCap records and reconstructs full-body movement as 3D motion-capture data. It is free, open-source software for researchers, animators, athletes, and creators. Capture can use two or more standard webcams, GoPros, or smartphones; a printed ChArUco board synchronizes camera feeds and defines the 3D coordinate system. Users can also record video offline on mobile devices and import it later for processing. Results can be exported in formats including CSV, FBX, and .blend files. A Blender add-on loads processed recordings into Blender as a rigged skeleton. Processing happens locally, and the homepage says video data does not leave the user's machine. A backend server download supports headless machines, remote capture rigs, and API use. The download page identifies the current release as alpha. Optional anonymous usage pings may include IP address, timestamp, and camera information, but users can disable them in the GUI. The project directs questions to Discord and bug reports or feature requests to GitHub. Its post-hoc guide notes that RTMPose produces 3D data but does not currently have working Blender export.

visage|SDK gives developers face tracking, face analysis, face recognition and eye or gaze tracking for applications they build. Eye-tracking outputs include 2D and 3D pupil coordinates, eye closure and rotation, gaze direction, and a calibrated point in screen space. The maker describes the tracker as working with standard cameras, including during occasional occlusion or when a subject turns away. The SDK can run online or offline, in the cloud or on a device. The maker says photos, names and similar personal data are not captured, stored or processed by default. It lists support for Android, API, iOS, Linux, macOS, web and Windows, along with Unity integration for face masks and games. Samples, guides and documentation are included to help with integration. The maker presents use cases including driver monitoring, robotics, education, marketing and UX, shopper research, academic research and assistive technology. A free evaluation license is available by contacting the maker; no duration is stated. Applications require a valid license key, and commercial terms vary by business model and use. Pricing is available on request.
