There are two display windows. The window on the left is the perspective view of a fighter plane "taken with" a virtual camera. You can create camera motions by changing its parameters such as eye-point, look-at-point and viewing angle. To make changes to the camera view, drag the mouse with the left button pressed within the display window. The effect of the mouse movements is dependent on the selected input mode. Orbiting and panning/tilting the camera is accomplished with moving the mouse in all four directions -- up/down and left/right. Truck and zoom is achieved with moving the mouse up and down. Dolly occurs when you move the mouse left and right.
The window in the top-right corner is a "third-person" view of the model (fighter plane) along with the perspective view volumne created with the left display window's virtual camera. The model remains static while the view volume changes according to the changes made in the left display window.
