Good-visibility computation using graphics hardware

Madern Leandro, Narcís 08 October 2010 (has links)
Aquesta tesi tracta del disseny, implementació i discussió d'algoritmes per resoldre problemes de visibilitat i bona-visibilitat utilitzant el hardware gràfic de l'ordinador. Concretament, s'obté una discretització dels mapes de multi-visibilitat i bona-visibilitat a partir d'un conjunt d'objectes de visió i un conjunt d'obstacles. Aquests algoritmes són útils tant per fer càlculs en dues dimensions com en tres dimensions. Fins i tot ens permeten calcular-los sobre terrenys. / In this thesis we design, implement and discuss algorithms that run in the graphics hardware for solving visibility and good-visibility problems. In particular, we compute a discretization of the multi-visibility and good-visibility maps from a set of view objects (points or segments) and a set of obstacles. This computation is carried out for two-dimensional and three-dimensional spaces and even over terrains, which in computational geometry are defined as a 2.5D space.
