Hi Aurelien,
It seems that already works! I attached code...
Code:
_qtViewer = new osgGenerals::ViewerQT(this);
ui.OSGRenderLayout->addWidget(_qtViewer);
_qtViewer->updateCamera(center,eye,up);
_qtViewer->setSceneData(_mainLogic->getRootGroup());
_qtViewer->startRendering();
Thank you!
Cheers,
Aitor
