Why does only Regular_triangulation_2 inherit the function, but others redefine it?
In Regular_triangulation_3, the type of the second parameter of move() function is Gt::Weighted_point_3. But the type in the function inherited from Triangulation_2 is Gt::Point_2. They do not match.

There is a move() function in Triangulation_2, Triangulation_3,
Delaunay_triangulation_2, Delaunay_triangulation_3 and

Regular_triangulation_2?

There is, it is inherited. Just call it with your regular triangulation and it will work.

    you need to explicitly call move (documented in the base class
    Triangulation_2 [1]) each time you want to update a weight.
    Note that a Vertex_handle is not valid when its vertex becomes hidden.

    It should not be hard to write a member method function update_weight.

        Anyone? Please. The regular triangulation in my algorithm needs

        thousands of times. I got to find an efficient way. Indeed, my

        right now is  for each update of a single vertex information , I
        cleared all
        vertices of the regular triangulation and reload all vertex
        information
        again. While this worked, but it was too time-consuming. Please
        help if you
        can. Thanks a lot.
