3) Consider the transformation graph shown in the figure below in which the geometric transformations Q21 and Q31 are defined with respect to an evolving reference frame. The composed homogeneous transformation matrix Q31 is the following: \begin{equation*} Q_{31} = \begin{bmatrix} -1/2 & -1/2 & \sqrt{2}/2 & 40 \\ 1/2 & 1/2 & \sqrt{2}/2 & 200 \\ \sqrt{2}/2 & \sqrt{2}/2 & 0 & -20 \\ 0 & 0 & 0 & 1 \end{bmatrix} \end{equation*} a) Determine the expression of the homogeneous transformation matrix, Q21, that allows to go from the first reference frame, R?, to the second one, R2, by applying the TRPY convention using evolving reference frames. The origin of R?is located at coordinates (100, 50, 20) with respect to R1, and y2 points into the sheet (to the back). b) Using the previous transformations, find the homogeneous coordinates of point P with respect to R2. P(2,4,6) is initially defined with respect to R3.
