lil confused

Hey Guys,

    i'm trying to a mesh for ocean that has 2x vertices at boundaries. i'm
lil confused with tris.


   Here is where the vertices and tris are setup.


gran = 0.1f;  // this actually sets the no of vertices/tris in a mesh (or
LOD). 0.1f is set for testing. it'll produce a square mesh with 9
vertices(3x3) and 8 tris .

    uint maxjd = (uint) (len * gran);
    uint maxj = maxjd + 1;
    uint maxid = (uint) (wid * gran);
    uint maxi = maxid + 1;

 for(uint j = 0; j < maxj  ; ++j)
    {
      for(uint i = 0; i < maxi ; ++i)
      {
        verts.Push(csVector3 ((i * wid / maxid), oHeight, (j * len /
maxjd)));
        norms.Push(csVector3 (0, 1, 0));
        cols.Push(csColor (0.17f,0.27f,0.26f));
        texs.Push(csVector2((i * wid / maxid) / 1.5, (j * len / maxjd) /
1.5));
      }
    }


     for(uint j = 0; j < maxjd; ++j)
        {
          for(uint i = 0; i < maxid; ++i)
          {
            tris.Push(csTriangle ((int)(j * maxi + i),
                        (int)((j + 1) * maxi + i),
                        (int)(j * maxi + i + 1)));
            tris.Push(csTriangle ((int)(j * maxi + i + 1),
                        (int)((j + 1) * maxi + i),
                        (int)((j + 1) * maxi + i + 1)));


                       //  debug  code
csPrintf("\nFirst  tri x= %d y=%d z=%d\nSecond tri x= %d y=%d z=%d",
(int)(j * maxi + i),
(int)((j + 1) * maxi + i),
 (int)(j * maxi + i + 1),
(int)(j * maxi + i + 1),
(int)((j + 1) * maxi + i),
 (int)((j + 1) * maxi + i + 1) );
                     //  debug code
          }
        }


after executing, debug code results  ( for one oceancell)

First      tri x=0 y=3 z=1
Second tri x=1 y=3 z=4
First      tri x=1 y=4 z=2
Second tri x=2 y=4 z=5
First      tri x=3 y=6 z=4
Second tri x=4 y=6 z=7
First     tri x=4 y=7 z=5
Second tri x=5 y=7 z=8

i can't figure out how these tris are working. they are not xyz for sure.
