This … 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 ...

Many algorithms for computing Delaunay triangulations rely on fast operations for detecting when a point is within a triangle's circumcircle and an efficient data structure for storing triangles and edges. In two dimensions, one way to detect if point D lies in the circumcircle of A, B, C is to evaluate the determinant: When A, B, C are sorted in a counterclockwise order, this determinant is positiv… WebApr 1, 1998 · One of the main characteristics of this new algorithm is its generality: it can be simply extended to triangulate point sets in any dimension. The technique adopted is very efficient and presents a subquadratic behaviour in real applications in E 3 , although its computational complexity does not improve the theoretical bounds reported in the ...
