To provide an adequate user interface to the large amount of geometrical and alphanumerical date coupled to the geometries, the 3D interaction in the virtual environment is combined with 2D interaction techniques using a portable touchscreen computer. Therefore, the consequences are analyzed, when the scenegraph structure of the underlying VR system is applied to the design of the 2D interface to the engineering data. This paper describes methods of using a scenegraph-oriented approach for structured interaction and information display in a virtual engineering application.
