Voronoi diagram algorithm (Fortune’s sweepline)

2009-06-11 Thread Captain___nemo
Hi, I am implementing Voronoi diagram to find out the nearest location in a map visually. Right now I want to do this using integer coordinates (x,y) only in a canvas. Problem is- I am really confused about this algorithm. I read the Computational Geometry book, few more theory on Fortune's

Captain___nemo: Isn't it possible to implement Voronoi diagram using Fortune's algorithm without multithreading or hash map? Multi-threading isn't part of Fortune's algorithm. Multi-threading can be confusing, but it's better for you to learn to feel at home using hash maps (named dicts in

Robert Kern: You can see a mild modification of Fortune's original C code here: http://svn.scipy.org/svn/scikits/trunk/delaunay/scikits/delaunay/Voro... That's C++; C++ makes simple things hard and hard things possible :-) In Python that code may become much shorter (and slower). Bye,
