Alright, I updated the pvx file some, just the correct coordinates.
<?xml version="1.0" ?>
<pvx>
<Process Type="client" />
<Process Type="server">
<!-- Tiled wall in Kitware -->
<EyeSeparation Value="0.065"/>
<Machine Name="CTL"
Environment="DISPLAY=:0.4"
Geometry="2560x1600+0+0"
FullScreen="0"
ShowBorders="0"
LowerLeft="-1.524 -0.381 -1.524"
LowerRight="1.524 -0.381 -1.524"
UpperRight="1.524 1.524 -1.524"/>
<Machine Name="CTR"
Environment="DISPLAY=:0.5"
Geometry="2560x1600+0+0"
FullScreen="1"
ShowBorders="0"
LowerLeft="-1.524 -0.381 -1.524"
LowerRight="1.524 -0.381 -1.524"
UpperRight="1.524 1.524 -1.524"/>
<Machine Name="CBL"
Environment="DISPLAY=:0.6"
Geometry="2560x1600+0+0"
FullScreen="1"
ShowBorders="0"
LowerLeft="-1.524 -1.524 -1.524"
LowerRight="1.524 -1.524 -1.524"
UpperRight="1.524 0.381 -1.524"/>
<Machine Name="CBR"
Environment="DISPLAY=:0.7"
Geometry="2560x1600+0+0"
FullScreen="1"
ShowBorders="0"
LowerLeft="-1.524 -1.524 -1.524"
LowerRight="1.524 -1.524 -1.524"
UpperRight="1.524 0.381 -1.524"/>
</Process>
</pvx>
Attached is one image for reference. I can clearly the two images with an
eye separation of 0.065, but for some reason, I see both the images with
stereo glasses on. Any more ideas?
Lance (CC'd) had an idea that maybe, we can do passive stereo rendering as
well. Would you recommend that given our projectors here do support active
stereo? I am still trying though to make it work with active stereo. Is
there someway to define the viewpoints in the pvx file? Also, is there some
kind of a schema for this pvx file published somewhere?
Thanks for all your help!
