torial Chap 2: Geometric transformations Question 1: ose that you have a cube whose center is located at (10.0, 12.5, 13.5). Describe how would rotate the 8 vertices of the cube according to 45 degrees about its z-axis at its own center Question 2: Give: 6.1 The matrix necessary to perform the transformation from (a) to (b). 6.2 The matrix necessary to perform the transformation from (b) to (c). Question 3 Why do we use homogeneous coordinates in computer graphics systems like OpenG
