Abstract. This article describes two approaches for computing the line-of-sight between objects in real terrain data. Our purpose is to find an efficient algorithm for combat elements in warfare simulation such as soldiers, troops, vehicles, ships, and aircrafts, thus allowing a simulated combat theater.

Keywords: Line-of-sight algorithm; terrain model; GIS; real-time visualization.
