Enrichment and Reuse of Geometric Models

We present a method for navigating in geometric models and enrich them with structure and context information. We offer dedicated views for this information, develop strategies to navigate in them and focus on the tight coupling between manipulations in these views. This coupling means that information in one view is emphasized in another view and requires an analysis of visibility and recognizability of information. Our system, which we refer to as the ZOOM STRUCTOR allows to enrich a geometric model with context information and to modify the structure of a geometric model. To cope with the navigation problems arising in the exploration of large models, we apply Fisheye-techniques. This enables us to present relevant objects in detail while maintaining the global context. The application of Fisheye techniques in the structure view (2D Fisheye zoom) and in the geometryview (3D Fisheye zoom) unifies the navigation.
