Bottom convex hull
WebThe convex hull is the area bounded by the snapped rubber band (Figure 3.5). A formal definition of the convex hull that is applicable to arbitrary sets, including sets of points that happen to lie on the same line, follows. DEFINITION The convex hull of a set S of points is the smallest convex set containing S. WebAn Example.
