Abstract: In this project, our goal is to design a flipping algorithm for computing the Voronoi diagram of simple polygons. As preparation towards designing a flipping algorithm, we re-implemented the ear cutting algorithm of using a standard geometric library COAL. This new Implementation is compatible with COAL, We have designed...
