Hand tracking Researchers are developing hand tracking Software that will allow computers to track and recognize detailed hand movements for batter human-computer interaction. One three-dimensional hand model under investigation is constructed from a set of truncated quadrics (see figure) For example the calm of the hand consists of a truncated elliptic cylinder, capped off by the upper half of an ellipsoid. Suppose the palm of the hand is modeled by the truncated elliptic cylinder, capped off by the upper half of an ellipsoid. Suppose the palm of the hand is modeled by the truncated cylinder 4x2/9 + 4y2 = 1, for 0 < z < 3. find an equator of the upper pair of an ellipsoid corresponds with the top of the cylinder. if the distance from the top of the located cylinder to the top of the ellipsoid is 1/2.
