From VTK documerntation:
<br/>"vtkCylinderSource creates a polygonal cylinder centered at Center; The axis of the cylinder is aligned along the global y-axis."
<br/>
<br/>
</div> So to achieve what you want translate output of vtkCylinderSource (which is polidata) height/2 along y-axis which will place beginning of the cylinder at origin, then rotate it about x (90 degrees ) to have axis of the cylinder aligned with  Z axis.
