Dear all,

For an application, I need to wrap facet_angle,facet_size,cell_size, etc… into a struct , call it Data, where the user can just do:

Data my_data;

my_data.cell_size = 0.1

my_data_radius_edge_ratio = 2.

and so on. In the trivial case where all the parameters are double, as one can simply do:

struct Data{

double cell_size, cell_radius_edge_ratio;

};

However, I’m not able to find a solution in case the user may want to use (for instance) a variable cell_size, like in this example (https://doc.cgal.org/latest/Mesh_3/Mesh_3_2mesh_implicit_sphere_variable_size_8cpp-example.html#_a6).

In that case, what will be the type of cell_size in my own struct Data ? I only know it’s a boost named parameter, but I can’t see an elegant way to make both options (double and named parameter) available without hardcoding them.

Best regards,

Marco
