WebFeb 27, 2003 · We propose a new linear time algorithm to represent a planar graph. Based on a specific triangulation of the graph, our coding takes on average 5.03 bits per node, and 3.37 bits per node if the graph is maximal. We derive from this representation that the number of unlabeled planar graphs with n nodes is at most 2 n + O (log n ), where 5.007. WebJun 26, 2007 · We give a deterministic algorithm for triangulating a simple polygon in linear time. The basic strategy is to build a coarse approximation of a triangulation in a bottom-up phase and then use the information computed along the way to refine the triangulation in a top-down phase. The main tools used are the polygon-cutting theorem, which provides us … chuck taylor all star berkshire sneaker boot

WebMar 2, 2024 · A polygon is planar by definition. If you have points in 3d space that are not co-planar then it's not a polygon and the algorithm won't apply. For example, the algorithm needs to be able to test whether a certain point is on one side or the other side of a line defined by two other points. Such a test makes sense in 2d but not in 3d. http://homepages.math.uic.edu/~jan/mcs481/triangulating.pdf
