Hello,<br>
<br>
I’ve start to work intensively with the VRPlugin from git-master and want to get some feedback. First of all it works almost great :-). As a tracking system I’m using A.R.TrackPack2 with two infrared cameras and their VRPN server implementation.<br>

To be able to compile that Plugin some modifications were necessary:<br>
* As mentioned in this post (<a href="http://www.paraview.org/pipermail/paraview/2012-February/023816.html" target="_blank">http://www.paraview.org/pipermail/paraview/2012-February/023816.html</a>) the proxy API undergone some changes. But it seems, that the author of this post mixed up the parameter order. He referred to proxy name and proxy group. But it has to be swapped...<br>
* Not important to me but required to compile without errors: In vtkVRUIPipe.h the flag QTSOCK is checked for existence. I had to put it in manually ("#define QTSOCK 1"). Don't know why.</blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
Further modifications was necessary in the the vtkVRStyleTracking in order to update the HeadPose. The proxygroup name must be changed to "views". The group name "interactorstyles" in the post mentioned above is NOT working, otherwise the plugin crash, since no proxy or property can be found and the pointer are still NULL after configuration.<br>
<br>
But so far, I was able to use the VRPlugin in ParaView in a two-side VE and I've got the feeling, that virtual object placed in front of the screens... :-)<br></blockquote><div><br></div><div>Very nice. </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
Now, I have a kind of problem. When I am moving parallel (left to right) to the screens, I can observe a sort of rotation which can be not described as moving parallax. It seems, that the rotation point lies in the center of my projection displays. Object which came out of screen "standing" not on the same position. They are flying around. So, my question is addressed to experienced Virtual Reality user: Is this described behavior right or not?<br>
</blockquote><div><br></div><div>If it feels like it rotating around the center of your projection screen reasonably then it means that stereo is working! if it is too much then there is a problem of some coordinate transformations. </div>
<div><br></div><div>Let us know if you need some further help. </div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
