Currently FlightGear uses only one instance of <tt>osg::Viewer</tt>, which is used by CameraGroup to manage the slave cameras. Supporting CompositeViewer would require modifying {{flightgear file|src/Viewer/fg_os_osgviewer.cxx}} and creating some kind of wrapper class that manages the CompositeViewer instance and assigns a CameraGroup to each <tt>osg::View</tt>. It's also important to note that currently all FG subsystems assume there is a single instance of [[Howto:CameraGroup talks|CameraGroup]]. | Currently FlightGear uses only one instance of <tt>osg::Viewer</tt>, which is used by CameraGroup to manage the slave cameras.

{{Note|Jules has already created a custom view manager implementation (Sview) that supports multiple independent instances, so this step might be obsolete by now.}} | |||
The first step would be to port the view code to SimGear so it can be used and known by the Compositor and Canvas. The view manager ({{flightgear file|src/Viewer/viewmgr.cxx}}) currently has some hardcoded assumptions, so it would either need to be rewritten to remove them or a new interface for the Views could be created specifically for the Canvas Camera View. | The first step would be to port the view code to SimGear so it can be used and known by the Compositor and Canvas.
