[Paraview] Possible Bugs in CAVE mode??

[Stephan Rogge]

Hi,

yeah. It does help. But honestly I do have some doubts that this is the best
way to provide eye separation control. Since PVX is
used only at startup this parameter is fixed and all PV scenes running with
that configuration have to use it. In my case I use 
different scenes with different scales (cm or m). I cannot provide one eye
separation for all scenes. And to use one 
configuration file for each scale of scenes feels very cumbersome. In my
opinion the state file is a better place for that 
parameter.

BTW: Is it planned to modify OffCenterProjection computation to consider the
eye angle? 

Best regards,
Stephan

Hi Stephan,

There was a slight change in that we can now specify eye separation in the
pvx configuration file. You can set the eye seperation as.

<pvx>
 <Process Type="client" />
  <Process Type="server">
  <EyeSeparation Value="0.065"/>
 <Machine Name="Front"
.....

Hope this helps

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
