Hello,
the problem is that I want to use a embedded viewer (gtk), too. I
guess it doesn't work with the composite viewer. Or is it possible?
sorry, I'm not sure.

Two Viewports with one Camera
Hi,

Ok. I try the slave variant.
I have a additional question. When I use two different cameras
and three viewports, how would you implement this. Two viewport
have the first camera and the third viewport has the second
camera.
My idea is something like this:
// Camera 1 osg::Camera* cam1 = new ...
slaveCam1->setViewport(...);
// Slave Camera 1 osg::Camera* slaveCam1 = new ...
slaveCam1->setViewport(...);
// Camera 2 osg::Camera* cam2 = new ... cam2->setViewport(...);
cam2->addChild(scene);
// RootNode // Camera two as a part of the scene graph. Is this
clever? osg::Group* root = new ... root->addChild(scene);
root->addChild(cam2);
// Viewer osg::Viewer* viewer = new ...
viewer->setSceneData(root); viewer->setCamera(cam1);
viewer->addSlave(slaveCam1);
Is this the right way? And what is your commendation to use
different camera manipulators. That means, what can I do when I
want to use a manipulator for the second camera (the camera in
the root node).
My idea is to write a GUIEventhandler. This should check the
mouse position and give the viewport or the camera and then I
calculate the new position like the trackball manipulator. That
is the approximate idea.
Do you want something different from what happens if you run
"osgcompositeviewer cow.osg". There, each view can have its own
manipulator.

Hi Martin,
I'm a bit confused by the thread, but as a general note you
shouldn't go attempting to use two separate Viewport per
Camera. The OSG fully supports slave Camera that can share
scene graphs and share the same graphics context, so it's
straight forward to implement and manage, the osgViewer design
has been specifically designed to make this type of usage as
simple as possible.
Robert.

Hello all,
I would like use two viewports in my application and one
camera. Is this
possible? I think, the normal way is to define the viewport for
a camera like: camera->setViewport(...)
Is the only way to define camera, copy the camera and set
the viewports
separatly for every camera? The main problem is when I change
the camera settings, I have to copy the camera again.
Cheers
