REGION INTERVISIBILITY IN TERRAINS [PDF]
International Journal of Computational Geometry & Applications, 2007 A polyhedral terrain is the graph of a continuous piecewise linear function defined over the triangles of a triangulation in the xy-plane. Two points on or above a terrain are visible to each other if the line-of-sight does not intersect the space below the terrain. In this paper, we look at three related visibility problems in terrains.
