WebThe DeWall algorithm, though not in widespread use, features a unique divide-and-conquer paradigm and was a major inspiration behind this work. Due to the exponential growth of Delaunay triangulations in high dimensions, none of the above-mentioned algorithms are intended to scale past six or seven dimensions. In fact, this failure to scale to ... WebMar 1, 1997 · The Many algorithms have been proposed for the DT of a set of points in Ez, E3 or E A Delaunay triangulation algorithm, 20 called the Dewall algorithm, can be used to simplify greatly the merging phase and provide a general divide and conquer solution for pointsets defined in any dimensionality.
