I asked a couple of days ago on how to apply the method described by Preparata and Shamos for a set of points in R^m, but I have not received a single answer. It looks that the methods described in this book can be applied to R^2 only. When somebody asked this question a while ago, I suggested using Linear Programming instead of "shooting" rays. A lot of people criticized Linear Programming because "the complexity of the method described by Preparat and Shamos is O(n)". Well, solving a linear program with three constraints and n variables is O(n). So, again, I insist that using Linear Programming is better than "shooting rays" in the region specially that it gives the representation of the given point in terms of the corner points. -Samer
