HELICOPTER SIMULATION was developed by a 15-year-old student. The user directs the helicopter where to go with the pointing device, which controls the position of the black arrow on the screen. The window at the top shows the changing topography of the terrain below as the helicopter flies over it (Actual terrains were obtained from Landsat maps.) A third window keeps track of the helicopter’s altitude, direction and speed. The variety of events that can be simulated at the same time demonstrates the power of parallel processing.
