Yes, I do know. You can't. A classical mathematical theorem says that any

Hi,
Best thanks for your answers and solutions!
Now I got the vertices to be able to sort them
in a Grid-Like structure I decided the using
of a TreeSet and implement a Comparator,
which will not work in that way.
may anybody of you know how to make point3f comparable?
I got a hint from another
Yes, of course, However it does give you an array of Object[] rather than
Point3f[] which can be annoying.

Mike

Yes. Add each point to a HashSet. The set will only hold one copy of each
point. Then iterate through the set putting the points into a new array.
Set set=new HashSet();
