I'm a PhD student in IT at the University of Tallinn and a complete newcomer to JReality and I am trying to setup a simple small-sized prototype of CAVE System. It will consist of 2 walls and one floor (table). The actual testing environment is composed with 3 19" displays (as in the first picture below), but the final one will be made with 122x92cm backprojection screens.
My test machine (the one for the final system will be much empowered version of this, but still only one machine with several graphic cards to control the full system) is actually :
Corei5 Quadcore CPU
2xQuadro600 Nvidia graphic cards
8 Gb ram
OS : Ubuntu 12.10
3x19" Display
1x22" display (for the main control)
The display are runned on the dual heads of the Quadro600 cards as Separate X display.
I run and configured ParaView in the test environment and it worked perfectly (of course with only anaglyph stereo, but well enough to learn the configuration steps necessary for the final system) as you can see in the picture :
I actually have 2 main problems and questions.
1) First of all, i don't seem to achieve in any way to run the cave-demo example that is included in jreality, nor in any other way. I tried to follow the setup steps indicated in the CAVE tutorial, but when i start it, the only thing i obtain is the Viewer window on my control display, and nothing at all in the other 3.
* while modifying the settings files, i tried to figure out how the output is distributed among the different displays (usually and in paraview i've been using :0.1 :0,2 to define the separate display, but in the several config files here in jreality i still can't find where it is done.
* the server name in the clients.dat file, how should they be properly specified?
Basically i'm being quite clueless on how to proceed at all, any help would be seriously welcomed!
2)The second main question deals with the physical setup that we will have to adopt for the final system. A picture explains it better than a lot of words i think, and here it is
. One of the screens will have a "flap" that will disappear behind the other screen, so it will be hidden in the external frame. I would therefore like to reposition the coordinates of the "truncated" screen so to have anyway the complete scene perception looking at the center of the small cave. In paraview i managed to do that easily changing a couple of coordinates in the config file (the example in the first picture also shows it, it is not that well visibile in the picture and because the displays frames, but it seem to be working properly). Now, before designing and projecting the whole frame, we would like to know if this is also possible to do in JReality, as it is gonna probably be the software we will use mostly.I hope i explained everything properly and to hear something soon from you,
thanks a lot in advance,
