Hi, I derived a widget in Qt from QGLWidget, based on the code presented here: https://gitorious.org/mahjong-night/mahjong-night/blobs/master/mahjong-night/client/tablewidget.cpp
initializeGL(), resizeGL() and paintGL() are exactly the same, I removed everything else to have just basic functionality where I load a 'cessna' model. That worked fine, then I replaced 'cessna' model with four quads - creating four walls of the room (left, right, top, bottom) and using viewer.getCamera()->setViewMatrixAsLookAt() everything was ok. When I added: Code: osgViewer.getCamera()->setProjectionMatrixAsFrustum(-0.5 + x, 0.5 + x, -0.5 + y, 0.5 + y, nearPlane - z, 100.0); osg::Matrixd cameraTrans; cameraTrans.makeTranslate(x, y, z); in paintGL() just before viewer.frame(), I can zoom in and zoom out and move the viewpoint left-right, top-bottom but the result is not even close to the one I achieved using only openGL. Thank you!
