WebJan 1, 2015 · The DeWall algorithm presented by Cignoni et al. [9] is a typical decoupled parallel Delaunay triangulation method. The DeWall algorithm includes two main phases. In the partition phase, partition walls are generated to divide the input vertices into some groups. In the merging phase, the generated sub-meshes are merged.

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…
