Enrichment for Reuse of Geometric Models

We present a method for navigating in geometric models and enrich them with additional information. This enables us to adapt geometric models to different purposes and thus to reuse them. We offer dedicated views for the structure and context information as well as for the geometric model, 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 makes it possible 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. The application of Fisheye techniques in the structure view (2D Fisheye zoom) and in the geometry view (3D Fisheye zoom) unifies the navigation.
