No 3D Model, X Y Z translational axis returns NaN

[GoogleCodeExporter]

What steps will reproduce the problem?
I tried to install the latest version 120220 on OSX 10.7. It launches but then 
(once WiiServer is started up and paired, and WiiCamera is showing me the three 
dots, it) does not show me the 3D model, and the X Y Z translational axis are 
returning NaN (thus not functional). I use the WiiMote as webcam. Used with the 
same system a previous version of linux track correctly.

I append the log of the ltr_gui:

it is like it was looking for the TrackIR (that i don't own), and then outputs

Where does linuxtrack (ltr_gui and WiiServer) store all the preferences? i 
found a .linuxtrack folder in my user directory and some 
com.yourapplication.linuxtrack folders, but is there a complete list of files 
to throw away in order to have a new fresh version of linuxtrack?

Thanks

Hello Giovanni,
thank you for the report... I've checked the changes, but between those two 
versions nothing changed in the parts of code responsible for tracking.

I'd ask you for some clarification - you say the X,Y,Z are NaN; how about the 
angles (pitch, roll, yaw)? Do they work?

The logfile messages are normal - the verbose TrackIR search is there to help 
resolving some spurious TrackIR problems and the nonexistent key messages are 
OK too; in the past, there was only one symetrical limit for each axis 
(Pitch-limits,...), while now there are two (Pitch-left-limit, 
Pitch-right-limit).

As for the preferences, there are two places; the main one is the .linuxtrack 
directory in your home, namely linuxtrack.conf file. The other one is used only 
to store window positions, so they should pose no problems whatsoever.

Having said that, looking at your preferences, there doesn't seem to be any 
problem with them; I also tend to provide some "backwards compatibility", so 
the new version either understands the old format, or if it is not possible, it 
will provide a safe default.

At the moment, I'd ask you to conduct the following tests:

 - does this happen consistently? Meaning, every time you start the ltr_gui? (no need to restart the Wii server)

 - open the terminal and try the following commands:
{{{
  > export LINUXTRACK_DBG=t
  > cd "/Users/Giovanni/Desktop/X-Plane 10 Demo/ltr_gui.app/Contents/MacOS"
  > ./ltr_gui
}}}
It should start linuxtrack GUI in the mode that logs the values from the 
"driver".
It should give me some pointers to where do those NaNs get there...
Just start the tracking, and when you see those NaNs, stop it again.
When done, please send me the logfile contents to take a look...

 - try starting ltr_gui, go to the Misc tab and check the "Use legacy pose computation method" button and then start the tracking - does it change anything?

 - what happens when you press Recenter button while the NaN is reported?

Kind regards,

Michal

Thanks for the quick reply. When I'll come back from work, i'll try the 
commands you provided, and send you the log file. As for now, i remember that 
when I start the wii camera, Pitch Roll and Yaw angles are ok; are properly 
displayed in the "edit sensitivities" window, with values that appear to be 
consistent.

X Y Z translation return NaN during all the recording of the camera. When i 
recenter the window (in the 3D model), it continues to show a blue screen 
(maybe the 3D model is loaded properly, but the X Y Z position are out of the 
Field of View).

Thanks

Giovanni

Yes, it happens every time I start the ltr_gui.

I tried both with the "Use legacy pose computation method" option activated and 
de-activated, but returns me always NaN in the sensitivities window for X, Y, 
and Z translation.
I attach the logs obtained with the LINUXTRACK_DBG=True option.
"Log" is the first attempt (at the end I tried to press the "Recenter" button 
but nothing happens (in the 3D visualization).
"LogWithLegacy" is the second attempt (with the "Use Legacy Pose Computation 
Method" option activated.

Finally I attach the X-PLANE error picture I sent you via mail 
"Errorxplane.png".

I'm running on OSX 10.7, have Xcode installed, maybe I can compile ltr (quite a 
newbie in that).

Do you think the problem is the WiiRemote as camera or the OS version I'm 
currently running?

Thanks a lot for the help! Let me know if I can do/test something else.

Hello Giovanni,
I can reproduce the problem, which should simplify the debugging...
I'll keep you posted,

Hello Giovanni,
here is the fix - so far it seems to cure the problem for me...
The zip file contains libltr.dylib.0
Ctrl-click on the ltr_gui, select the show package contents; go to Contents, 
Frameworks and replace the library with the new one.
Let me know how it works...
Kind regards,

Michal

Thank you so much,
fantastic job, the custom library fixes everything!!!!!The ltr_gui is working 
properly, the 3D model is back again and so are the X, Y, Z translations.

The X-PLANE plugin now launches properly, but I noticed that it is not 6DOF (it 
has Pitch and Yaw, but misses roll, maybe is an issue of X-PLANE 10), another 
thing that i noticed, is that in the ltr_gui the movements are smooth and very 
natural; in X-PLANE the view wobbles and bounces so much. What is the 
difference between the x-plane plugin and ltr_gui? (i've PilotView Plugin 
installed too)

Thank you!

Hello Giovanni,
thank you for the good news...

The 6DOF plugin for XPlane on Mac is yet to be released; right now I'm 
implementing facetracking and when this is released, 6DOF will be included.

Bouncing view might be caused by several things - Pilotview is adding movements 
according to the G forces, also there used to be thing called Cinema Verite, 
which does something similar (it was option in the XPlane). Other than that, 
I'm not sure what could be the cause of this.
Let me know, if you find something...
Kind regards,

Michal

Sorry to tell you that in the new release the issue is not fixed, i even tried 
to replace the library with the one you gave me, but x-plane plug-in is still 
corrupt and the 3D model window of ltr_gui does not load the 3D cockpit.

Thank for the report - I'm sorry I missed it; there is just too much going on 
right now... Hopefully the newest release would fix this problem too.
Kind regards,

Michal

Hello,
I'm closing this issue, as Beta 7 seems to cure the problem (as you reported in 
issue 19). Feel free to reopen it, should the problem show up again...
Kind regards,

Michal
