[vtkusers] get an arbitary oblique slice through volume with vtkImageReslice

[David Feng]

The vtkImagePlaneWidget class will let you interactively 
rotate/scale/etc a slice plane through a volume and show you the results 
as you go.  I think you just need to click on the boundaries of the 
image to start the different manipulations.  You can get the sliced 
values out from the widget via GetResliceOutput(), or something 
similar.  I think you can set the position of the plane programmatically 
as well. 

If you want to get dirty with vtkImageReslice, I believe what you'll 
need to do is make a vtkPlane and connect it via SetInputInformation().  
The ResliceAxesDirectionCosines allow you transform the plane (or 
whatever reslice structure you use) into a different coordinate space 
(patient space to world space, for example).  In your case, it's 
probably easier to manipulate the vtkPlane directly.
