Hello everyone,

I want to mark some vertices(facets,edges...) of a triangulation, but I
don't know how.

part of my codes are:

list<Weighted_point> lwp;
Alpha_shape_3  as(lwp.begin(), lwp.end(), 0, Alpha_shape_3::GENERAL);
Alpha_shape_3::Finite_vertices_iterator vit;
for (vit = as.finite_vertices_begin(); vit !=
as.finite_vertices_end();vit++)
{
        if(as.classify(vit,0)==Alpha_shape_3::REGULAR)
        {
                ##### mark vit; #####
        }
}

and then I want to do:

for(all vit)
{
        if(vit was marked)
        then(......)
}


Can anyone tell me how to mark a Vertex_handle(Facet,Edge...)? I read
the reference of triangulation but couldn't find a solution. Thanks.

Best regards,
Lin
