Hello J.P.,
both cameras have the same graphics context (gc). Here the complete part of the
code with the views:
osg::ref_ptr< osgViewer::View > view0 = new osgViewer::View;
view0->setSceneData(root);
view0->setDisplaySettings(ds0);
view0->getCamera()->setViewport(500,0,500,800);
view0->getCamera()->setGraphicsContext(gc);
osg::ref_ptr< osgViewer::View > view1 = new osgViewer::View;
view1->setSceneData(root);
view1->setDisplaySettings(ds1);
view1->getCamera()->setViewport(0,0,500,800);
view1->getCamera()->setGraphicsContext(gc);
osg::ref_ptr< osgViewer::CompositeViewer > viewer = new
osgViewer::CompositeViewer;
viewer->addView(view0);
viewer->addView(view1);
Cheers
Martin
