Definition3.6 The convex hull of a finite point set PˆRd forms a convex polytope. Each p2Pfor which p=2conv(Pn fpg) is called a vertex of conv(P). A vertex of conv(P) is also called an extremal point of P. A convex polytope in R2 is called a convexpolygon.

WebConvex Hull. A convex hull of a shape is defined as: In mathematics, the convex hull or convex envelope for a set of points X in a real vector space V is the minimal convex set containing X . Wikipedia visualizes it nicely using a rubber band analogy, and there are some good algorithms to compute it.

WebNow there are three cases to consider: If m L < M R, then every point in Q lies strictly below the line y = m x, so p is a vertex of the upper hull. If m L = M R, then the line y = m x passes through a point in L and a point in R, and no point in Q is strictly above that line. So p lies on an edge of the upper hull, but it is not a vertex. damita jo i'll save the last dance for you Algorithms that construct convex hulls of various objects have a broad range of applications in mathematics and computer science.
