WebMay 22, 2024 · A convex hull uses the same principle as convex polygon applied to set of points. For instance, a convex hull is the smallest convex polygon containing all the points of a set. One of the purpose of a convex hull is to prune a specific area in a plane. It is mostly used in computer graphics, geometry and navigation.
