Hi Carsten,
you are right, that is what I mean.
The thing is that, we have 3 machines to drive 6 displays which constitute a
'Tiled Display Wall'.
We have another computer as a cluster server, to run exact OpenSG
applications, and the previous 3 server nodes run passive windows to show
the results.
Thank you and Shree, we have overcome the major troubles. However, the thick
frame borders of displays split the scene, and bring certain visual errors.
I now have a possible solution, but more tests are needed.
first, I will configure the two displays of one computer as the separate
views (now is in Twin View mode),
then, I will start two passive windows which are a bit larger than the
screen area, but their view ports are smaller which will fit the screen area
well.
I hope you can understand my plan, anyway, I will implement this idea in
these days, and report if this works.
Good luck with me~
