Hi Aashish,<br><br>here is the paraview state file part related to the tracking :<br><br> <VRConnectionManager><br> <VRPNConnection name="Wtrack" address="Wintracker0@localhost"><br> <Tracker id="0" name="sensor"/><br>
</VRPNConnection><br> </VRConnectionManager><br> <VRInteractorStyles><br> <Style class="vtkVRTrackStyle" proxy="2128" property="EyeTransformMatrix"><br> <Tracker name="Wtrack.sensor"/><br>
</Style><br> <Style class="vtkVRTrackStyle" proxy="2128" property="CameraPosition"><br> <Tracker name="Wtrack.sensor"/><br> </Style><br> </VRInteractorStyles><br>
<br>and here's my .pvx file<br><br><?xml version="1.0" ?><br><pvx><br> <Process Type="client"/><br> <Process Type="server"><br> <EyeSeparation Value="0.035"/><br>

Also, it seems that the quaternion values sent by the vrpn server of the tracker work well in Model Transform Matrix, they are of no use in the headtracking. What i feel is that the visual of the user is fixed on the object in the center of the screen, and when i move my head the perspective changes fine but always being stuck with the same target point. I thought it might be a natural behavior of paraview, but still i couldn't figure it out.<br>
<br>May I ask if you know if the crystal eyes stereo effect has the same problem as the anaglyph one on the server screens?<br><br>Best,<br>H<br><br><div class="gmail_quote">2013/1/11 Aashish Chaudhary <span dir="ltr"><<a href="mailto:aashish.chaudhary@kitware.com" target="_blank">aashish.chaudhary@kitware.com</a>></span><br>

I'm using ParaView3.98 RC1 and the in the vrpn server i converted
the units in meters as for the vrpn standard, so i guess they should
somehow be the right ones.<br>
Tomorrow from the office I can send you the PVX and the state files,
now I don't have them available.<br></div></blockquote><div><br></div></div><div>Would it be possible to use / build the ParaView from the master branch. We have couple of nice features there and made some improvements in the code. </div>

My feeling while testing on the test-system is that the headtracking
lets me change the position of the head a bit around the object, but
that I don't achieve a full movement. So for example, if i stand in
front of the receiver and then i move on top of it (towards -Z), i
don't see the object from above (or in the table-screen as i would
expect), but i see a upper-front perspective only, like if the
transform matrix of the view cone was changed, but somehow not the
position of the user.<br></div></blockquote><div><br></div></div><div>If you move your head on the top of object you should see the top view of the object. Now if your object is in the front of the projected plane, then you should be able to move even inside it. If it is on the back of the projected plane, then it won't. </div>

It might be just a wrong feeling given by the small system or maybe
the positioning of the object, but at least this far it doesn't give
at all the proper immersive feeling.<br></div></blockquote><div><br></div></div><div>It depends on the size of the object and its location. Only after looking at your state file and PVX file I can give a precise answer.</div>

As a side question still related to my system, i noticed the
anaglyph stereo goes completely wrong in the screens, while it is
correct (and completely different) in the control display, any
suggestion on that? (soon i'll have to switch to paired projectors
and passive stereo, so i would like to avoid the same problem
there).<br></div></blockquote><div><br></div></div><div>Hmm..I am aware of this bug. </div><div class="im"><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Btw, tomorrow I'll send you the files and a sample of the data I get
from the tracker.<br>
Thanks again for your time!<br></div></blockquote><div><br></div></div><div>Sure that would be awesome. </div><div class="im"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
