With the projectors and cables we have at the CAVE at VT, the active stereo is happening at the projector. It is being sent two separate video channels, 1 for left eye and one for right eye. Basically, at the computer side it is like passive stereo. Glxgears does not have this type of stereo option." This is why glxgears doesn't work in stereo mode here.</span><br><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">David, I have tried that configuration. See </span><a href="https://github.com/faizabidi/VE_Project/blob/master/cave-stereo.pvx" style="font-size:12.8px">HERE</a><span style="font-size:12.8px">. Yes, both sections are driving the same set of pixels, so the coordinates must be the same. But I get the same issue like before. I am kind of confused here now. I am still trying to figure it out. Thanks for looking into this. If you run into any new ideas, please do let me know.</span></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Mar 28, 2016 at 1:09 PM, David E DeMarle <span dir="ltr"><<a href="mailto:dave.demarle@kitware.com" target="_blank">dave.demarle@kitware.com</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><div><div><br>Cool that's easy enough to try.<br><br></div>@Faiz edit your pvx like so:<span class=""><br><Machine Name="CTL"<br> Environment="DISPLAY=:0.4"<br> Geometry="2560x1600+0+0"<br> FullScreen="1"<br> ShowBorders="0"<br> LowerLeft="-1 -1 -1"<br> LowerRight="1 -1 -1"<br> UpperRight="1 1 -1"/><br> <Machine Name="CTR"<br> Environment="DISPLAY=:0.5"<br> Geometry="2560x1600+0+0"<br> FullScreen="1"<br> ShowBorders="0"<br> LowerLeft="-1 -1 1"<br> LowerRight="1 -1 -1"<br> UpperRight="1 1 -1"/><br></span></div>becomes<span class=""><br><Machine Name="CTL"<br> Environment="DISPLAY=:0.4"<br> Geometry="2560x1600+0+0"<br> FullScreen="1"<br> ShowBorders="0"<br> LowerLeft="-1 -1 -1"<br> LowerRight="1 -1 -1"<br> UpperRight="1 1 -1"/><br> <Machine Name="CTR"<br> Environment="DISPLAY=:0.5"<br> Geometry="2560x1600+0+0"<br> FullScreen="1"<br> ShowBorders="0"<br></span> LowerLeft="-1 -1 -1" #NOTE the change here to make it match CTL<span class=""><br> LowerRight="1 -1 -1"<br> UpperRight="1 1 -1"/><br><br></span></div>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.<br><br><br><br><br><div><div class="gmail_extra"><span class=""><br clear="all"><div><div>David E DeMarle<br>Kitware, Inc.<br>R&D Engineer<br>21 Corporate Drive<br>Clifton Park, NY 12065-8662<br>Phone: <a href="tel:518-881-4909" value="+15188814909" target="_blank">518-881-4909</a></div></div>

Each tile shows left and right eye interleaved in time or color or pixel offset. The displays are not mean to be different eyes for the same tile as you want them to be. That is why we have a single eye separation for the whole config but you want a left eye or right eye designation for each output.<br><br></div>@Aashish - Faiz would need to hack ParaView right ?
