A method for mass-production butchering of a beef chuck roll includes locating an anterior side and a posterior side of the chuck roll, and making a first series of cuts into the chuck roll along lines not intersecting the anterior and posterior sides. More particularly, the data packer accumulates write data received from lower bandwidth clients for delivery to a high bandwidth memory interface. Then, a three-dimensional plane P1 including these three-dimensionally restored e2L and e4L is found, and the edge e3L residing beyond a predetermined angle range with reference to the cross angle of 90\xb0 crossing the epipolar line is projected to this three-dimensional plane P1, thus three-dimensionally restoring the edge e3L. The processor, under proper software instructions, moves the windows toward the destination location on the screen based on the tilt angle. In preferred embodiments, the described feeding pattern and diets are fed in conjunction with one or more weight loss agents.
