[osg-users] OSG Architecture
Hi, Please tell me if my understanding is correct?If create a Geode called 'room' and inherit a node from room called 'sofa'. So room-sofa. Then if we rotate room, would the sofa also rotate,?. But if we rotate sofa then room should not rotate.How can we establish an architecture like that?...Is it possible in OSG?..Please help. ... Thank you!

[osg-users] Model not scene
I am using OSG with QT..Made the OSG viewer in QWidget Layout as QGridLayout. My model is vanished, not seen. Please tell me what I am doing wrong. For creatting the view in Qt my code is below CSGroup* root = new CSGroup(); ViewerWidget* viewWidget = new ViewerWidget(m_Modelling_Designs-m_TabWidget-widget(0), root, fileName) ; QGridLayout *layoutForModel = new QGridLayout; layoutForModel-addWidget(viewWidget); m_Modelling_Designs-m_TabWidget-widget(0)-setLayout(layoutForModel); viewWidget-show(); For adding model into scene snippet is below. /// osg::ref_ptrosg::Node axes = osgDB::readNodeFile(C:\\SUJAN_C_DRIVE\\OSG_DATA\\OpenSceneGraph-Data-3.0.0\\axes.osgt); scene-addChild( axes); gView = (CSGraphicsView*) (addViewWidget( createCamera(0,0,-0.5,0.5), scene )); QGridLayout* grid = new QGridLayout; grid-addWidget( gView, 0, 0 ); setLayout( grid ); /// Please help why my model is not appearing.

Re: [osg-users] Translate problem
Dear Nick thanks a lot for your code snippet. I appreciate it. I am after
custom mouse event handling, I dont want TrackBallManipulator as I am more
interested to manage events from Qt.

Hi Sujan,
viewerWid-getView()-getCamera()-setViewMatrix(::osg::Matrix::translate(1000.5,
0.0, 0.0));
this code is wrong. Also, you have attached TrackballCameraManipulator so
it will fight you against the translation you do.
If you want to translate an object in the scene, then use
osg::MatrixTransofrm as parent of your object and there set the
translation. If you want to change the ViewMatrix, then set the inverse of
your world translation, but also update the CameraManipulator, so something
like:
osg::Matrixd myMatrix = osg::Matrix::translate(1000.5, 0.0, 0.0);
viewerWid-getView()-
getCamera()-setViewMatrix(osg::Matrix::inverse(myMatrix));
viewerWid-getView()-getCameraManipulator()-setByMatrix(myMatrix);
If you are after custom mouse management, then I would inherit from
TrackballcameraManipulator and override handle - look in the code od
TrackballCameraManipulator::handle since it is the closest to your wish of
mouse handling
Hope this helps a bit

Hi Sujan,
here is how I would do it:
//Let load the model:
osg::Node* model = osgDB:: readFile();
// Create MatrixTransform on top of it
osg::MatrixTransform* mxt = new osg::MatrixTransform;
// create the scene
mxt-addChild(model);
viewer-setSceneData(mxt);
Now, having it like this, by modifying the matrix in the MatrixTransofrm,
you can move the loaded object in the scene as you are doing with
onPan(double dx, double dy), and don;t touch the view matrix
something like:
void onPan(double dx, double dy)
{
osg::MatrixTransform* mxt =
dynamic_castosg::MatrixTransform*(viewer-getSceneData());
mxt-setMatrix(osg::Matrix::translate(1000+dx, 0, 0))
}
you get the idea? Hope it helps

I don't know why this code didn't crash, I think it should. Anyway, you
should create an instance of the CSGraphicsView somewhere within
createCamera:
CSGraphicsView* gView = new CSGraphicsView;
gView-setGeometry(x, y, w, h);
traits-inheritedWindowData = new osgQt::GraphicsWindowQt::**WindowData(
gView );
...
or you can pass an instance of the CSGraphicsView to the
osgQt::GraphicsWindowQt constructor.

Call base class implementation in a case where you need to retain
original functionality:
void CSGraphicsView::mousePressEvent(QMouseEvent *e)
{
if(e-button()==Qt::LeftButton)
{
QMessageBox msg;
msg.setText(Mouse pressed);
msg.exec();
}
else
GLWidget::mousePressEvent(e);
}
Also, calling frame on paintEvent might not be enough. You should also
call frame on every user input, on all mouse and keyboard events for
example... or you can mount a QTimer and make it call frame at some
interval.

Re: [osg-users] OSG Build with Visual Studio 2010
Thanks dear Robert. I got one more doubt how can we build OSG using cmake. I am getting errors that it's not getting bcc32 compiler. Although I got Visual C++ 2010 compile it should take that. And moreover I just installed bcc32 5.5 also. Now it's giving error it's not able to run a simple test. Please help.

Thank Sujan That means that you have built OSG in release mode only. You must build both release debug version of OSG if you want to build the examples (or your project) in Debug mode.
