Hi guys!

I am facing one problem here. I am sure you guys can help me.

                       20

                    19   18

                  17  16  15

               14  13  12  11

             10  9   8   7    6

           5    4     3   2  1  0  

I am triangulating this surface. I want to select just the red vertices. As you can note, I just need the inner vertices of this surface. I could do it mannually, but if I want to change the mesh density later, I will have to pick all of them manually again later.

Can someone help me? 

Tks

Can you guarantee that the mesh vertices will always be so nicely ordered? Because if not you'll need to take a geometric approach. If however you need to generate the lists {1,2,3,4}{7,8,9}{12,13}{16} then there's lots of ways of doing that.

tks a lot David! It worked.

I tried with different number divisions, and they worked properly. It seems that the order is always the same.

tks again!
