CGAL 4.12.1 - 3D Mesh Generation
MeshCriteria_3 Concept Reference

## Definition

The Delaunay refinement process involved in the template functions make_mesh_3() and refine_mesh_3() is guided by a set of elementary refinement criteria that concern either mesh tetrahedra or surface facets. The refinement criteria for tetrahedra are described through the concept MeshCellCriteria_3 while the refinement criteria for surface facets are described by the concept MeshFacetCriteria_3. The concept MeshCriteria_3 encapsulates these concepts.

Has Models:
CGAL::Mesh_criteria_3<Tr>
MeshFacetCriteria_3

CGAL::make_mesh_3()
CGAL::refine_mesh_3()
