Typedefs
CGALTriangulation2Ddefs
Description
CGAL data structures used for 2D Delaunay meshing.
Define CGAL_INEXACT to use Exact_predicates_inexact_constructions kernel
otherwise the more robust but much less efficient
Exact_predicates_exact_constructions will be used.
Define CGAL_HIERARCHY to use hierarchical Delaunay triangulation which is
faster but uses more memory than the standard Delaunay triangulation.
