In particular this will be the key we use in our algorithm to evaluate the $\alpha$-structures. We will describe more precisely how to evaluate the characteristical $\alpha$ in the "Alpha Structures Implementation" section 4.2.
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. However, this algorithm does not consider the ... http://www.personal.psu.edu/cxc11/AERSP560/DELAUNEY/8_Divide_and_Conquer_DeWall.pdf
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…
