vtkPicker..

[K.R.Subramanian]

I am using the vtkPicker object to pick all actors intersected.  I am
trying
to retrieve the actors intersected using the GetActors() method
(followed
by GetNextActor() from the vtkActorCollection method, but I get nil.
I looked
at the collection object and it has 3 items in it (which is what it
should be in
my application).

I am also able to use the GetActor() method to get the closest actor
intersected (and
the pick position also looks reasonable).

I assumed you iterate with GetNextActor() method of vtkActorCollection
until you get
nil to retrieve all of the actors that were intersected.

Any ideas what I am doing wrong?
