Algorytm tworzenia triangulacji z wyspami zagnieżdżonymi
Języki publikacji
Abstrakty
Islands are composed by closed arcs without intersection with each other. The relationship between islands can be either nesting or mutually independent. Through the analysis on nesting relationship among the islands, the arcs compositing islands are divided into four basal types, moreover, every type is provided an algorithm for calculation. The inner of islands is automatically identified according to the types of arc segments and then a triangulation algorithm with constrained condition was carried out. According to previous method, complex triangulations are structured. Proved by experiments, the efficiency of the algorithm is mainly determined by the efficiency of formatting delaunay of triangulation.
W artykule przedstawiono analizę związków zagnieżdżonych, występujących między wyspami, poprzez którą dokonano podziału łuków, tworzących wyspy na cztery podstawowe kategorie, a ponad to dla każdej z nich określono sposób obliczenia. Wnętrze wysp jest określane automatycznie, na postawie typów łuków, co w wyniki pozwoliło określić algorytm triangulacji. Badania eksperymentalne potwierdzają skuteczność algorytmu, wynikającą z zastosowanej triangulacji Delong.
