Hi Faiz,
Few things:
1| You have two projectors per wall each covering half of the wall
2| You are trying to do active stereo on each half part of the wall
3| You put glasses on and you see both left and right eye on the half wall
from the same projector
If this is the case, it sounds like your active stereo is not working. Are
you sure your driver is setup up correctly? Before you try to work on
cluster setup, just try working on one projector for debugging purposes. If
I were you I would do this:
1) Just use PVX to run on one projector (half wall)
2) Make sure your driver is setup correctly. If this is linux try running
glxgears in stereo mode (
http://manpages.ubuntu.com/manpages/karmic/man1/glxgears.1.html)
3) If 2) works then something is wrong with VTK/ParaView/Config somewhere.
4) Make sure that your active glasses are working meaning that they are
syncing with the transmitter which is connected to the node
Hope this helps.
