[Paraview] Possible Bugs in CAVE mode??

[Stephan Rogge]

Hello (again),

regarding the cave stereo issue I was able to put an debug message into the 
vtkCamera and noticed that EyeSeparation is an incredibly small value
(1E-332).
 It seems that somewhere the eye separation value is lost which results in
two 
identical projection matrix and this yields a monocular vision. That would 
explain why stereo is not working....

@Nikhil, if I get you right, you are involved in the VR development of PV?

Thanks,
Stephan
