[vtkusers] Multiple actors with same image

[Roger Blum]

Hello,

I would like to display hundreds of image actors (bitmaps / symbols) in a 3D 
scene with Tcl/Tk.
Every actor has it's own position, but all have the same symbol. It should 
be possible to select/interact with each actor.

What kind of data source do I choose (vtkPoints, vtkPointsSource, 
vtkBMPReader, ..)?
Which filters do I have to apply ?
Do I have to create a vtkImageMapper, and what kind of actor do I use then?
Or can I simply use the vtkImageActor?

I 'm experimenting with vtkGUI 1.0 which is great for this purpose.

Thanks in advance for your help!

Roger
