3 point tracking = headset and controllers. The rest of the body is predicted.
6 point tracking = headset, controllers, hip tracker, and foot trackers.

Oculus does not make hip or foot trackers, so you need either kinect, or to use the completely separate HTC trackers and lighthouses and hack the two playspaces together. If you have Pimax, Index, or Vive, these devices use the lighthouse system already, so you just need three extra trackers.
