How did the "bullet time" in The Matrix come out?

When they shot the "bullet time" shot, 120 cameras were accurately placed on a route set by the computer tracking system, and then the shutters of these cameras began to take pictures according to the sequence and time interval pre-programmed by the computer, and then all the photos taken from all angles were scanned into the computer, and the computer virtually repaired the difference between two adjacent photos, so that the continuous and smooth motion of the subject under the 360-degree shot could be obtained, and finally the computer took pictures.
