Hi,

Similar questions have been asked multiple time in the past but I couldn’t find a proper answer to this issue.

I am trying to implement the 4 panes view thing (axial, coronal,  
sagittal and 3D(surface render)) using four vtkRenderWindow. I want the axial view to  
update itself each time I move the vtkImagePlaneWidget in the 3D view.  
The same applies for each axis.

Right now, I am using three vtkImagePlaneWidget in the 3D view and  
, if I move one vtkImagePlaneWidget in the 3D view, its  
corresponding planar view should also move.  
I came across vtkSynchronizedRenderWindows and  
vtkParallelRenderManager, but it is not clear to me that I need this.

Regards,  
Aish
