You must be creating some other vtkObjects from somewhere else in your code
that are not being cleaned up.
Can you set a breakpoint in the vtkObject::vtkObject constructor and see
where you are creating them from? You should only hit that breakpoint from
your Init_3D method if that is the only place where you are creating them
from...
