Convex hull algorithms

Dynamic convex hull

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).

What are convex polygons

👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which at least one of its interior angles is greater than 1

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
