Hi Elias, The osg::Transform is the base class for creating transforms in the scene graph, there are a collection of subclasses that you can use, osg::MatrixTransform and osg::PositionAttitudeTransform being the most commonly used, either of these can work for you. Have a look at the osganimation example to see how to use these classes, or just do a search in the examples for MatrixTransform/PositionAttitudeTransform.
