The
createCube()
method is mostly the same as the one we used in previous examples. This
time, however, we add normals to each vertex, as shown in Figure
11-4
. Apart from that, nothing
has really changed.
@Override
public void
update(
float
deltaTime) {
angle += deltaTime * 20;
}
In the
update()
method, we simply increase the rotation angle of the cube.
