\brief The class `Poisson_mesh_domain_3` derives from `Labeled_mesh_domain_3` for the handling of `Poisson_reconstruction_function`.
|
||||
|
||||
This class has a constructor taking a labeling function. It has also a static template member
|
||||
function that acts as named constructor:
|
||||
<ul><li>`create_Poisson_mesh_domain()`, to create a domain from a `Poisson_reconstruction_function`</ ul>
|
||||
<ul><li>`create_Poisson_mesh_domain()`</li>, to create a domain from a `Poisson_reconstruction_function`</ul>

\tparam BGT is a geometric traits class that provides

the basic operations to implement intersection tests and intersection computations through a bisection
