Hi,

I've been trying to setup a two projector lab so that I can play vrml files on the screen.  The setup is a curved screen, though fixing for distortion isn't really a priority, with two projectors that have an overlap such that each projector displays on 3 of 5 total panels.  However, each projector only displays 2/3 of the middle panel, such that 1/3 of the center panel is overlapped by both projectors.  The display is run by a single computer with three graphics cards(one for the monitor and one for each projector), not a cluster.  I am trying to find a way to configure my code to display on such a screen.  I've tried using TiledClusterWindow, though it seemed illogical to use it without a cluster, and I've tried to create multiple viewareas with limited areas of render but that hasn't allowed for complete usage of the screen, unless I am merely coding incorrectly, which is entirely possible.  So, my question stands, is there a way for me to code my display configuration such that the two overlapping projectors display only one image?  Do I have to go into the computer's settings to fix my problem instead?  Thanks for any help in advance.

Regards,
Matt

Hey,

I've actually managed to solve this problem myself since I posted.  Apparently, TileViewManager successfully solves my issue.  I'll post my bit of code to help anyone who may have this same problem in the future.

Engine {
jobs [
  DEF render RenderJob {
    windowGroups [
      WindowGroup {
        windows [
          LocalWindow {
     position 1688 130
        sample 4
        sampleFilterMode nicest
          ##fullScreen TRUE
          size 3200 1000
            views [
              Viewarea {
                lowerLeft  0 0
                upperRight 0.5 1
                modifier [
                  DEF Left TileViewModifier {
         left 0
         right .533
         bottom .2
         top .8
                  }
                ]
              }
              Viewarea {
                lowerLeft  0.5 0
                upperRight 1 1
                modifier [
                  DEF Right TileViewModifier {
         left .467
         right 1
         bottom .2
         top .8
                  }
                ]
              }
            ]
          }
        ]
      }
    ]
  }   
]
}
