the most flexible way is to use a ProjectionCameraDecorator to specify
the physical image plane in camera coordinates, for example:
camera ProjectionCameraDecorator
{
surface
[
-1195.0 -950.0 -2000.0,
0.0 -950.0 -2000.0,
0.0 950.0 -2000.0,
-1195.0 950.0 -2000.0
]
decoratee USE PerspCamGL
}
Probably start with Examples/CSM/Cluster/Simple-Multi which configures
2 side-by-side screens. As you change the surface corner coordinates you
can approximate you physical projection setup.
Examples/CSM/Common/system-native-cluster-multi-wall.osg is the screen
setup that contains 2 viewports with the decorators for the 2 physical
screens.
To translate the example to 'standard' OpenSG you can replace the
CSMClusterWindow by the MultiDisplayWindow and the CSMViewport by
the normal Viewport. The fields used (except clusterMode which is
specific to CSMClusterWindow) should map directly to the 'plain'
OpenSG classes. If not let me know.
