Ha, now you had me confused. As I said before I am going to remove points that are co-planar with all their neighbors, as it happens for example at roofs (did I already say my points are airborne LIDAR measurements?) . So I will have more and more points that are not used in the triangulation. I don't want to update a lot of point numbers each time I remove a point.
