3. A 2 x 2 x 2 cube has the eight vertices (+1, +1, +1). Show how to render the six faces of the cube with two triangle fans, by explicitly listing the vertices used for the triangle fans. Make sure that the usual CCW front faces are facing outwards. (There is more than one way to do this, but please use (1,1,1) as the first (central) vertex for one of the triangle fans.) 3.
