<div dir="ltr">Hi Faiz, <div><br></div><div>Few things: </div><div><br></div><div>1| You have two projectors per wall each covering half of the wall</div><div>2| You are trying to do active stereo on each half part of the wall</div><div>3| You put glasses on and you see both left and right eye on the half wall from the same projector</div><div><br></div><div>If this is the case, it sounds like your active stereo is not working. Are you sure your driver is setup up correctly? Before you try to work on cluster setup, just try working on one projector for debugging purposes. If I were you I would do this: </div><div><br></div><div>1) Just use PVX to run on one projector (half wall)</div><div>2) Make sure your driver is setup correctly. If this is linux try running glxgears in stereo mode (<a href="http://manpages.ubuntu.com/manpages/karmic/man1/glxgears.1.html">http://manpages.ubuntu.com/manpages/karmic/man1/glxgears.1.html</a>) </div><div>3) If 2) works then something is wrong with VTK/ParaView/Config somewhere.</div><div>4) Make sure that your active glasses are working meaning that they are syncing with the transmitter which is connected to the node</div><div><br></div><div>Hope this helps.</div><div><br></div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Mar 25, 2016 at 7:28 PM, Faiz Abidi <span dir="ltr"><<a href="mailto:fabidi89@vt.edu" target="_blank">fabidi89@vt.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div style="font-size:12.8px"><div><div><div><div>Alright, I updated the pvx file some, just the correct coordinates.<span class=""><span><br><br><?xml version="1.0" ?><br><pvx><br> <Process Type="client" /><br> <Process Type="server"><br> <!-- Tiled wall in Kitware --><br> <EyeSeparation Value="0.065"/><br> <Machine Name="CTL"<br> Environment="DISPLAY=:0.4"<br> Geometry="2560x1600+0+0"<br></span></span> FullScreen="0"<br> ShowBorders="0"<br> LowerLeft="-1.524 -0.381 -1.524"<br> LowerRight="1.524 -0.381 -1.524"<br> UpperRight="1.524 1.524 -1.524"/><span class=""><span><br> <Machine Name="CTR"<br> Environment="DISPLAY=:0.5"<br> Geometry="2560x1600+0+0"<br> FullScreen="1"<br> ShowBorders="0"<br></span></span> LowerLeft="-1.524 -0.381 -1.524"<br> LowerRight="1.524 -0.381 -1.524"<br> UpperRight="1.524 1.524 -1.524"/><span class=""><span><br> <Machine Name="CBL"<br> Environment="DISPLAY=:0.6"<br> Geometry="2560x1600+0+0"<br> FullScreen="1"<br> ShowBorders="0"<br></span></span> LowerLeft="-1.524 -1.524 -1.524"<br> LowerRight="1.524 -1.524 -1.524"<br> UpperRight="1.524 0.381 -1.524"/><span class=""><span><br> <Machine Name="CBR"<br> Environment="DISPLAY=:0.7"<br> Geometry="2560x1600+0+0"<br> FullScreen="1"<br> ShowBorders="0"<br></span></span> LowerLeft="-1.524 -1.524 -1.524"<br> LowerRight="1.524 -1.524 -1.524"<br> UpperRight="1.524 0.381 -1.524"/><br></div> </Process><br></div></pvx><br><br></div>I tried attaching an image for reference but my email didn't go through.
