i think you use osg::GraphicsContext::getCameras to obtain ptr to the
Cameras list, then add cameras to that list. i haven't tried it, that's
just looking at the API, but have been messing around with the osgViewer
API for the last week, and it looks like it oughtta work like that.

Hi charlie,
Actually i dont understand your solution because addCamera() method in
GraphicsContext is protected and i could not add cameras to it. In a
way i want to use single graphics context and i want to display
different views of same scene in same window. Each view will
completely cover full window, and i want to switch between one view to
another view. I may create multiple viewers each covering all render
surface and add them to CompositeViewer, however, CompositeViewer do
not have any mechanism to disable or remove views from it, so I could
not switch between views.
Thanks.
Aydin

Hi Aydin,
i'm no expert, but perhaps you could more directly address your
situation (single GC)
by having multiple cameras in the Cameras list, which is there in
osg::GraphicsContext:
typedef std::list< osg::Camera
<cid:[email protected]> * > Cameras
<cid:[email protected]>
