WebAug 15, 2024 · This convex hull (shown in Figure 1) in 2-dimensional space will be a convex polygon where all its interior angles are less than 180°. If it is in a 3-dimensional or higher-dimensional space, the convex hull will be a polyhedron. There are several algorithms that can determine the convex hull of a given set of points. WebNov 9, 2014 · In the Euclidean space $E^n$ the convex hull is the set of possible locations of the centre of gravity of a mass which can be distributed in $M$ in different manners. Each point of the convex hull is the centre of gravity of a mass concentrated at not more than $n+1$ points (Carathéodory's theorem).
