Abstract:V diplomski nalogi predstavimo problem Delaunayeve triangulacije na ravninski množici točk in njene pomembnejše lastnosti. Naredimo splošen pregled obstoječih metod izgradnje Delaunayeve triangulacije, več pozornosti pa namenimo metodi Delaunayeve triangulacije s prebirno premico, ki služi kot osnova algoritmu s prebirnim krogom. Glavni del diplomske naloge obsega podrobnejšo predstavitev vseh faz algoritma Delaunayeve triangulacije s prebirnim krogom, implementacijo tega algoritma in primerjavo hitrosti izvajanja z Žalikovim algoritmom s prebirno premico. Ugotovimo, da se poenostavljena verzija algoritma s prebirnim krogom obnese bolje od izvirne, a ne prehiti Žalikovega algoritma s prebirno premico.

Title:Delaunay triangulation with circle sweep
Abstract:A problem of computing the Delaunay triangulation of a set of 2D points and its related properties is considered in this thesis. An overview of existing computational methods is done at first. Focus is given to the sweep-line algorithm, which served as a basis for the circle-sweep algorithm. The central part of the thesis covers the presentation of the circle-sweep algorithm in detail, its implementation and comparison of spent CPU time in regard to the Žalik’s sweep-line algorithm. It was determined that the simplified version of the circle-sweep algorithm offers better performance in comparison to the original version, yet fails to surpass the Žalik’s sweep-line algorithm.
Keywords:Delaunay triangulation, algorithms, computer geometry
