Hi Sanat,
>http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgviewerQt/osgviewerQtContext.cpp<http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgviewerQt/osgviewerQtContext.cpp>
with this more simple example it would be easier to transit to osg::Viewer
you should know following - before you can derive from Viewer you should set
it as
with the call to setUpViewerAsEmbeddedInWindow
see what is does on Viewer to be prepared to be embedded:
GraphicsWindowEmbedded* Viewer::setUpViewerAsEmbeddedInWindow(int x, int y,
int width, int height)
{
setThreadingModel(SingleThreaded);
osgViewer::GraphicsWindowEmbedded* gw = new
osgViewer::GraphicsWindowEmbedded(x,y,width,height);
getCamera()->setViewport(new osg::Viewport(0,0,width,height));
getCamera()->setProjectionMatrixAsPerspective(30.0f,
static_cast<double>(width)/static_cast<double>(height), 1.0f, 10000.0f);
getCamera()->setGraphicsContext(gw);
return gw;
}
so in osg code you need to connect Viewer.
after that you would be able to create camera and add
setCameraManipulator(new osgGA::TrackballManipulator);
then add to camera your model, then add camera to viewer or directly to
viewere.
you may find complete simple code sample to use Qt and osg::Viewer here
http://hipersayanx.blogspot.com/2011/04/qt-openscenegraph-offscreen-rendering.html(
it's in spanish but for you most important is code - which I think you
will understand ). I found it by searching osg::Viewer and
setUpViewerAsEmbeddedInWindow there are other useful examples on the net,
but hope the one on the link will help you.
Regards
Sergey
