Vector Representing Position
A vector can represent an object's position in the Android 3D OpenGL ES world. In fact, in the
Orientation class from the example in Chapter 2, the object's position is a 3D vector represented by
the Vector3 class.
private Vector3 m_Position;
Graphically, you can see a vector representing an object's position in the 3D world in Figure
