The convex hull\ccIndexMainItemDef{convex hull} of a set $S$ is the smallest convex set containing $S$. The convex hull of a set of points $P$ is a convex polytope with vertices in $P$. A point in $P$ is an extreme point (with respect to $P$)\ccIndexMainItemDef{extreme point} if it is a vertex of the convex hull of $P$. \cgal\ provides functions for computing convex hulls in two, three and arbitrary dimensions as well as functions for testing if a given set of points in is strongly convex or not. This chapter describes the class available for arbitrary dimensions and its companion class for computing the nearest and furthest side Delaunay triangulation. \section{Classified Reference Pages} \ccHeading{Concepts} \ccRefConceptPage{ConvexHullTraits_d} \\ \ccRefConceptPage{DelaunayLiftedTraits_d} \\ \ccRefConceptPage{DelaunayTraits_d} \\ \ccHeading{Classes} \ccRefIdfierPage{CGAL::Convex_hull_d_traits_3} \\ \ccRefIdfierPage{CGAL::Convex_hull_d} \\ \ccRefIdfierPage{CGAL::Delaunay_d< R, Lifted_R >} \clearpage
