FaceReader's face model is defined in millimeters. By a projection of the 3D model to the 2D image FaceReader can derive where in real world coordinates the face is in the 2D image (and an estimated camera projection matrix). FaceReader's 3D coordinates are centered around the camera, the camera is at (0,0,0). Therefore, the 3D coordinates of the fitted model will tell you where the face is relative to the camera.
