<div>Hi Aashish,<br>
<br>
after some thinking (being my first system shaped this way i'm
having to get aquainted to the concepts still), I realized that
ok, the point at which the view is aiming doesn't have to move
indeed, and that the all problem seems to be due to the position
of the object in the screens.<br>
<br>
I hope you can figure out what i did wrong in the config file (i
bet the problem is there somehow). <br>
<br>
Best,<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>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>

<div bgcolor="#FFFFFF" text="#000000"> 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>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>

<div bgcolor="#FFFFFF" text="#000000"> <br>
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>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>
