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_cast<osg::MatrixTransform*>(viewer->getSceneData());
mxt->setMatrix(osg::Matrix::translate(1000+dx, 0, 0))
}
you get the idea? Hope it helps
Nick
