Hi,

I guess you mean this sample: 
http://public.kitware.com/pipermail/vtkusers/2004-April/073344.html


Just make the sphere invisible and visible only when you are picking.
Add

...
sphereActor->PickableOff();
sphereActor->VisibilityOff();  

and
...
 if (m_pvtkActorSelection)
 {
     m_pvtkActorSelection->VisibilityOn();
     m_pvtkActorSelection->SetPosition(picker->GetPickPosition());
 }

greets
  Ingo

The sphere is used as a marker for the pick. When the program start up,
the sphere is already in view at a corner of the cube. Is it possible to
make it invisible until user picks on the points?

Thanks! =)
