Given a cube with the size of 1 × 1 × 1 at its origin in Figure 2.11, determine the vertices of the object after the lengths along the x, y, z axes are scaled up by 2, 3, and 1, respectively.

Figure 2.11 Example of a scaling matrix of a 3D object. (a) Before transformation. (b) After transformation.
