seconds with respect to the vertical y axis. Note that there is an exit button that spans the
entire window width at the bottom of the window and that the program can be stopped by
pressing this button.
In the new few subsections, we will outline the fundamental underlying concepts and
graphical model specified by the program code in Figure 1 and show how this leads to
the 3D outputs of Figure 2. This will serve as an overview before these concepts and the
associated applications are discussed in more details in subsequent chapters.
