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. |
