CGAL::Convex_hull_projective_xy_traits_2<Point_3>

Definition

The class Convex_hull_projective_xy_traits_2<Point_3> serves as a traits class for all the two-dimensional convex hull and extreme point calculation function. This class can be used to compute the convex hull of a set of 3D points projected onto the xy plane (i.e., by ignoring the z coordinate).
