#include <CGAL/Convex_hull_projective_yz_traits_2.h>

Definition

Deprecated:
The functionality of this class has been generalized to other packages than 2D convex hulls. The more general class Projection_traits_yz_3 can be found in the 2D and 3D Linear Geometric Kernel. Note that the deprecated class was templated by a point class, whereas the new class is templated by a geometric kernel.

The class Convex_hull_projective_yz_traits_2 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 \( yz\) plane (i.e., by ignoring the \( x\) coordinate).
