Definition

template<typename Traits>
class CGAL::Homological_discrete_vector_field::Icosphere_object_io< Traits >

The class Icosphere_object_io is an intermediate IO class, used to produce a Mesh_object_io containing an icosphere (for Hdvf_duality with tetgen).

Template Parameters

Traits

a geometric traits class model of the HDVFTraits concept.
