Hi,
I'm using a simple class in order to render an OSG view into a Qt environment
and I'm having trouble trying to render a simple model.
Here is the constructor of the class I use :
Code:
OSGWidget::OSGWidget(QWidget * parent, const QGLWidget * shareWidget,
Qt::WindowFlags f):
QGLWidget(parent, shareWidget, f),
root(new osg::Group),
graphicsWindow_(new osgViewer::GraphicsWindowEmbedded(this->x(), this->y(),
this->width(), this->height())),
viewer_(new osgViewer::CompositeViewer)
{
float aspectRatio = static_cast<float>(this->width()) /
static_cast<float>(this->height());
osg::Camera * camera = new osg::Camera;
camera->setViewport(0, 0, this->width(), this->height());
camera->setClearColor(osg::Vec4(1.f, 1.f, 1.f, 1.f));
camera->setProjectionMatrixAsPerspective(30.f, aspectRatio, 1.f, 1000.f);
camera->setGraphicsContext(graphicsWindow_);
osgViewer::View * view = new osgViewer::View;
view->setCamera(camera);
view->setSceneData(root.get());
view->addEventHandler(new osgViewer::StatsHandler);
view->setCameraManipulator(new osgGA::TrackballManipulator);
viewer_->addView(view);
viewer_->setThreadingModel(osgViewer::CompositeViewer::SingleThreaded);
osg::Node * node =
osgDB::readNodeFile("/home/sisyphe/Programs/OpenSceneGraph-Data-3.0.0/cessna.osg");
root->addChild(node);
this->setFocusPolicy(Qt::StrongFocus);
this->setMinimumSize(100, 100);
this->setMouseTracking(true);
QTimer * timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(updateView()));
timer->start(10);
}
All the OSG stuff is done here and you can see in attachment how the cessna
model is rendered. It looks like if faces were rendered in wrong order.
I didn't find anyone having similar issue.
Is it related to Qt or something like face culling or normals ?
Thank you![/code]
