<div class="moz-cite-prefix">Hi Aashish, <br>
<br>
i took away the camera position and left only the EyeTransform
matrix to be controlled by the camera, i put a big object (10x) in
the middle of the scene and tested. <br>
<br>
An example to explain the problem i had :<br>
<br>
I move the head UP with the object "in front of me". The
perspective changes properly, but at the same time, instead of
going "down", the object comes up too. Shouldnt it be the
opposite?<br>
<br>

<div><font face="arial, sans-serif">You are trying to move
both the eye and the camera? The PVX files looks alright.
On your other point, when you move the eye (a point in
space) the rotation will not have any effect (rotation of
a point?) . But when you tilt your head towards left
(lets say 90 degree rotation) you images (from two
viewpoints) should be on top of each other. </font></div>

<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>

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>

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>

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>
