Hi Aashish, today i installed the master ParaView as you suggested.
There is something wrong with the GUI for the VRPlugin, and now it's not
possible to select anymore the type of the VR connection, not even
importing a state file. I solved that importing an older version of the
plugin, with that it works, but so i don't know it the problems are
fixed. (it took me a while to figure how to use the new FullScreen
option but then i managed, i was trying to put it in the Server process)
Now somehow once in a while, even after applying the right transform
matrix to the tracker data, i have the weird effect that once in a
while, the axis seem to randomly invert. So if until a second before it
was working fine with the headtracking around an object, suddenly it
gets wrong on all the four axis. I don't know if it might be a problem
of my tracker or is something in paraview.
As a test, I saved a working system state, went out of paraview and when
i restarted and restored the state, the axis were wrong again.
As a side effect, there is a XGrabKeyboard command to remove in the vtk
filevtkXOpenGLRenderWindow.cxx and if you don't remove it, when paraview
is running fullscreen you can't use the keyboard anymore, nor in
paraview nor in other applications.
Best,
Emiliano

Hi Aashish, perfect, thank you very much! I'll give it a try
tomorrow, and if it all works well i'll use it for a demonstration
on wednesday, just in time!
Great. Let us know if we can help.
Thanks,

Hi Emiliano,
I just wanted to let you know that recently we fixed couple of
minor bugs and now they are in ParaView master if you want to
give it a try.
Thanks

Hi,
I'm having some issues with headtracking in ParaView in a
3 screens environment (2 walls + 1 table). From the GUI
(and also from the config pvsm file, but equal results) I
tried to configure the following propertier connected to
the tracker.
a) Camera Position ( I mentioned it in a previous
message), the vrpn server doesn't seem to feed the proper
argument to the SetCamera function and so it doesn't work.
b) View Position : when i start the vrplugin it gives me
the following message :
Generic Warning: In
/home/hogan/projects/ParaView/ParaViewCore/ServerManager/Core/vtkSMPropertyHelper.cxx,
line 429
Call not supported for the current property type.
And nothing happens.
c) EyeTransformMatrix : close to be working, but when i
move my head around the screens, the object doesn't move
properly around the screens (while if i just move the
object with the mouse, it goes properly across the three
display, moving from one to another according to the
position)
d) ModelTransformMatrix : works properly
Which is the "official" procedure to do the headtracking?
Am I doing something wrong? The fact that it works
properly with the ModelTransformMatrix makes me think
that the vrpn server that i wrote for this tracker works
properly, so i don't get what else i shall modify to
properly track the head movement.
Connecting your sensor to the EyeTransformMatix is the right
thing to do for the head tracking. Is it possible that your
numbers are too small? When you move your head the position
of the object may not move that much depending on your object
is front of the projected plane or behind. If you can send me
your config file, state file and what values you are getting
from your sensor, I can provide you exact explanation.
Thanks,
Any hint is welcome before i go mad!
Best,
Emiliano
