The spheres inside the cylinder are generated dynamically, and included in the vtkRender one by one, i.e. each sphere has its own mapper, actor, etc. Therefore, simply using cutter or plane is unable to fulfill the slicing. </div><div><br></div><div>One thing I can imagine is that if I can get the data from the renderer, I can then apply cutter or plane to slice it.
