With the rapid development of the technologies of virtual reality (VR) and augmented reality
(AR), the accurate visual query of 3D objects which are closer to real world has become a …

The paper deals with the topic of efficient visibility analyses, its algorithms and performance
in context of the area shape and its size. Visibility analyses are fundamental component of …

For a set $ S $ of $ n $ disjoint line segments in $\mathbb {R}^{2} $, the visibility counting
problem is to preprocess $ S $ such that the number of visible segments in $ S $ from any …

Watchtowers are located on terrains to detect fires, military units are deployed to watch the
terrain to prevent infiltration, and relay stations are placed such that no dead zone is present …

Visibility computing is a basic problem in computer graphics, and is often the bottleneck in
realistic rendering algorithms. Some of the most common include the determination of the …
