[vtkusers] vtkPointHandleRepresentation2D or vtkPointHandleRepresentation3D

[Concetta Piazzese]

Hello there!
I have to place same seeds on 7 different slice of a volume. I use vtkimageviewer2 to select the slice  and seedWidget to place the seeds. Why if I use vtkPointHandleRepresentation2D the points coordinates are different from the ones that I get using vtkPointHandleRepresentation3D? What's the difference?
Do I have to use vtkPointHandleRepresentation2D and suppose the slice is a 2D image or i have to use vtkPointHandleRepresentation3D and suppose the slice is a 3d image (slab)? Which one is better?
The weird thing is that vtkPointHandleRepresentation2D appears to be the right one. Is that normal?
Thank you! And I'm sorry for my english!
Concetta
