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.
