Hi Sawsan,
   vtkOBBTree has a member function ComputeOBB. Perhaps you can use the
outputs from this to determine the location and orientation of the longest
axis. This information could then be used to locate and orient a plane:
vtkPlane and vtkClipPolyData or vtkCutter can then be used to clip or cut.

hope that helps, Dave P
