Function Documentation

template<class PolygonMesh , class Traits >
bool CGAL::is_strongly_convex_3 ( PolygonMesh &  pm,
const Traits &  traits = Default_traits 
)

determines if the vertices of a given polyhedron represents a strongly convex set of points or not.

A set of points is said to be strongly convex if it consists of only extreme points (i.e., vertices of the convex hull).

Template Parameters
PolygonMeshmust be a model of the conceptFaceListGraph.
Traitsmust be a model of the concept IsStronglyConvexTraits_3.

Implementation

This function implements the tests described in [2] to determine convexity and requires \( O(e + f)\) time for a polyhedron with \( e\) edges and \( f\) faces.
