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… WebThe algorithm requires computing the SCCs and then checking if there are any edges out of the SCC containing the town hall.
