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]>

I download and analyze the new osgViewer library. I realize that
CompositeViewer allows only adding Views but not enabling or disabling
or removing them. What i want to do is, generate multiple views
(possibly with more than one cameras-slaves) of same scene and during
execution only one of them will be active (for example, inside view of
car). During simulation, i want to change the active view (in the same
window) to another view (which may be outside view of car). It is
necessary to create two viewer and call frame() method of only one
that is active in that time to make this?
Thanks
Aydin

Hi Aydin,
I'm afraid you are demand a bit more from osgProducer::Viewer that is
provides for - its entirely geared around mananging one view onto the
scene, the multiple camera support is just to support multiple
coordinate graphics outputs such as used in sims.
The new osgViewer library now in Subversion now directly supports
multiple views on the same scene via the new CompositeViewer class.
This class allows you to compose your viewer from one or more views on
to one more scenes, with all sharing of using separate graphics
windows. Each of the different views can have its own camera
manipulator to allow independent view interaction, or you just set
each views main camera view matrix directly.
Robert.
