[Paraview] Mono and Stereo Rendering in the CAVE

[David E DeMarle]

Cool that's easy enough to try.

@Faiz edit your pvx like so:
<Machine Name="CTL"
           Environment="DISPLAY=:0.4"
           Geometry="2560x1600+0+0"
           FullScreen="1"
           ShowBorders="0"
           LowerLeft="-1  -1  -1"
           LowerRight="1    -1  -1"
           UpperRight="1    1   -1"/>
    <Machine Name="CTR"
           Environment="DISPLAY=:0.5"
           Geometry="2560x1600+0+0"
           FullScreen="1"
           ShowBorders="0"
           LowerLeft="-1    -1  1"
           LowerRight="1   -1  -1"
           UpperRight="1   1   -1"/>
becomes
<Machine Name="CTL"
           Environment="DISPLAY=:0.4"
           Geometry="2560x1600+0+0"
           FullScreen="1"
           ShowBorders="0"
           LowerLeft="-1  -1  -1"
           LowerRight="1    -1  -1"
           UpperRight="1    1   -1"/>
    <Machine Name="CTR"
           Environment="DISPLAY=:0.5"
           Geometry="2560x1600+0+0"
           FullScreen="1"
           ShowBorders="0"
           LowerLeft="-1    -1  -1" #NOTE the change here to make it match
CTL
           LowerRight="1   -1  -1"
           UpperRight="1   1   -1"/>

Both sections are driving the same set of pixels, so their world space
coordinates have to match. The only difference is the display number which
selects the video output. If you had multiple machines, you would have to
tailor your mpiexec call to ensure the the ordering, but since all are on
the same machine any process can directly draw to any display so it won't
matter.
