visage|SDK vs XR Animator

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.

XR Animator is a free tool for driving MMD or VRM 3D avatars from pose input. It uses MediaPipe and TensorFlow.js to detect poses from webcam video, and supports face, full-body, and combined face, body, and hand tracking. Full-body tracking can use a webcam or an image or video file. Face tracking supports 52 ARKit-compatible blendshapes. Users can record motion capture, export VMD, BVH, and glTF motion, and load VMD, FBX, and BVH motion files; FBX or BVH motion can also be exported to VMD. The scene can include 2D images or video, 3D panoramas, and .x or .glb objects. The web app works in major desktop and smartphone browsers, while Electron apps are available for Windows, Linux, and macOS. Android Chrome supports augmented reality. VMC protocol support and a frameless transparent background for capture apps are limited to Electron mode. The project notes that smartphones with limited processing power may be better suited to face tracking alone.
