Given a point P (2, 4, 8) and using the homogeneous representation: a. Calculate the corresponding transformation matrix and the coordinates of the transformed point P* if P is rotated about the x, y, and z axes at angles of 30, 60, and 90, respectively. b. If the point P obtained in part (a) is to be rotated back to its original position, find the corresponding rotation matrix. Verify your answer. c. Calculate P" if P is translated by d = 31 4j 5k and then scaled uniformly by S = 1.5. d. Calculate the orthographic projection of P, of P. e. Calculate the perspective projection P, of P if the center of projection is at distance d = 10 from the origin along z-axis.
