The dynamic convex hull problem is a class of dynamic problems in computational geometry. The problem consists in the maintenance, i.e., keeping track, of the convex hull for input data undergoing a sequence of discrete changes, i.e., when input data elements may be inserted, deleted, or modified. It should be distinguished from the kinetic convex hull, which studies similar problems for continuously moving points. Dynamic convex hull problems may be distinguished by the types of the input data and the allowed types of modification of the input data. (Wikipedia).

Computing Delaunay complex: Lifting to a paraboloid [Ondřej Draganov]
Short visual explanation of a construction of Delaunay complex via lifting to a paraboloid and projecting. This construction reduces the problem of finding the Delaunay complex of a d-dimensional point cloud to finding a lower convex hull of a (d+1)-dimensional point cloud. This video is
