29Description
30 CGAL data structures used for 2D Delaunay meshing.
31
32 Define CGAL_INEXACT to use Exact_predicates_inexact_constructions kernel
33 otherwise the more robust but much less efficient
34 Exact_predicates_exact_constructions will be used.
35
36 Define CGAL_HIERARCHY to use hierarchical Delaunay triangulation which is
37 faster but uses more memory than the standard Delaunay triangulation.
