Motion Analysis Cortex vs XR Animator

Motion Analysis Cortex is Windows motion-capture and analysis software for biomechanics, broadcasting, sports performance, game production, virtual and augmented reality, film, research, engineering, and rigid-object tracking. It provides body, face, and hand tracking, character and animation retargeting, cleanup tools, real-time output, and FBX, HTR, and C3D export. Cortex connects with Maya, MotionBuilder, Unity, and Unreal in real time or through data files. Cortex 10 adds Manus Meta glove tracking, marker templates, selectable batch processing, editable system objects, markerset-trimming scripts, and Rainbow HD camera support. A license includes Calcium Solver, SONIC Viewer, KinTools RT, DV Reference, Skeleton Builder, CamTrak, Motion Composer, and Continuous Calibration. Other integrations include Delsys and Noraxon EMG, Bertec and AMTI force platforms, MATLAB, LabVIEW, ROS, and VRPN. Motion Analysis lists clinical evaluation, research, animal studies, studio camera tracking, and robotics among supported uses.

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.
