I can't used the vtkConnectivityFIlter because when i apply it for my
meshes, it gives one color because it has just one component.

I didn't have a specific criterion, I just want a filter that allows me to
segment a mesh, and, surely, enable me to retrieve the cells and vertex
associated to each region. Because, i'm working for : local mesh refinement.
I don't have a specific mesh, i work on apple, bunny...All 3d mesh's format.
I used now the vtkOctree, and i succeed to subdivide my mesh to 8 segments.
But I have a little problem in the Mouse interaction that i put it in this
