Dear Tsai,
There is no visitor for points (mesh nodes) of a mesh region. The
more straighforward mean is to iterate on elements/face of a
region and then on points of element/face and paying attention
to repetitions of points (storing
the visited point in a dal::bit-vector for instance).

Dear Yves,
As we know, we can obtain a visitor for points of a mesh and
get their positions by
for (dal::bv_visitor i(mesh.points_index());
!i.finished(); ++i)
{
bgeot::base_node &pt = mesh.points()[i];
...
}
Therefore, I wounder if there is a means to obtain a visitor
for points of a mesh region.
sincerely
CC Tsai
