You can experiment with moving the teapot around in space, changing its size, and angle. Think about the order in which you need to combine the transforms to get a particular image that you want. For example, if you translate an image and then scale it, you’ll get a different effect to scaling it then translating it. If you want to rotate or scale around a particular point, you can do this in three steps (as with the 2D case above): (1) translate the object so that the point you want to scale or rotate around is the origin (where the x, y and z axes meet), (2) do the scaling/rotation, (3) translate the object back to where it was. If you just scale an object where it is, its distance from the origin will also be scaled up.
