Hi Sajjad,
There are asType functions is osg::Node, this has better performance then dynamic_cast ... for example you can do: osg::ref_ptr<osg::Switch> switch = group->asSwitch(); Now you are using a virtual table to get the right type: if the object is a Switch you will get the this-pointer of the Switch if it is not you will get 0. Usually there are always better ways then dynamic_cast, especially if you are the owner of the code.
