Is there sorting and tracking of 3D points?
For individual 3D points the Tracking Tools software does not provide tracking of points between consecutive frames, it will only return information about the markers found in the current frame. There is also no guarantee markers will be delivered in the same order from one frame to the next (no sorting). For 3D markers clustered into rigid bodies, the Tracking Tools software will identify and track the locations of the rigid body and its markers between frames.
