The class Implicit_to_labeled_subdomains_function_wrapper
is a helper class designed to wrap an implicit function which describes a domain by [p
is inside if f(p)<0
] to a function that takes its values into {1, 2}
and thus describes a multidomain: the subspace described by f(p)<0
is attributed the subdomain index 1
and the subspace described by f(p)>0
is attributed the subdomain index 2
.
Note that for the 3D mesh generator [f(p)=0
] means that p is outside the domain. Since this wrapper has values into {1, 2}
, both the interior and the exterior of the periodic domain described by the input implicit function are meshed, thus yielding a periodic mesh of the entire canonical cube.
 Template Parameters

Function  provides the definition of the function. This parameter stands for a model of the concept ImplicitFunction described in the surface mesh generation package. The number types Function::FT and BGT::FT are required to match. 
BGT  is a geometric traits class that provides the basic operations to implement intersection tests and intersection computations through a bisection method. This parameter must be instantiated with a model of the concept BisectionGeometricTraits_3 .
