Hi Andreas,
 
    Thanks for the prompt reply. Appreciate it very much. I know that if you use
CGAL::cartesian<double> , it is using reference counted, but if you use
CGAL::simple_cartesian<double>, it is not using reference counting. But still, it does not provide me with
anyway to change the location/position of that vector or point_2 easily.
 
I am trying to code a movable mesh application, and required that points in the triangulation move around their physical position, hence trying to figure out how to make them change their location/position easily.
 
Thanks in advance to anyone who can provide me with any insight, thanks!
 
regards
Calvin
