It may help if you clarify what you want to do with this union of  
actors. I don't think you can directly do the Actor1 + Actor2 = Actor3  
thing you're implying.

You can create a vtkActorCollection to gather actors and pass them  
around as one object. Depending on the type of data you have, you  
could also use the vtkAppendFilter, or vtkAppendPolyData to group your  
data into a single grid before creating a single mapper and actor.

Maybe someone else knows some other tricks,
