WebApr 4, 2014 · Sweepline Delaunay algoritm can be O (n*log (n)) not O (log (n)). With small number of points an implementation with worst case O (n^2) can be faster than O (n*log (n)) implementation. One reason can be that the O (n*log (n)) algorithm might have to use a hierarchical data structure. Constantly adding and removing points and balancing a tree ... WebMar 6, 2024 · I am going through the tutorial outlined here using typescript.
