PublicationSimulationstechnik für Produktentwicklung und Fabrikplanung.( 1993)
;Spur, G. ;Krause, F.-L.Mertins, K.Simulation systems are gaining an increasing influence. While different solutions are still being used on the way from the idea of a product to the production plant, comprehensive modelling will become feasible in the future. -
PublicationWissensbasierte Rekonstruktion von Volumenmodellen( 1990)
;Spur, G. ;Schiller, U. ;Timmermann, M. ;Jansen, H.Krause, F.-L.Limited system consistency in handling 2-D and 3-D modelers is among the serious critical aspects of modern-day CAD systems. The reconstruction method enables straightforward and familiar 2-D input methods for orthogonal views to be conveniently interlinked with the well-known virtues of solid modelling. One problem associated with his technique is, however, the unavoidable generation of excess 3-D elements resulting from projections and only barely identifiable using algorithmic techniques. An approach is described which, with the aid of knowledge-based methods, enables a far-reaching automatic reconstruction of volume models and thus helps to reduce the problem of generating inconsistent models. -
PublicationMultirepresentation-based geometrical modeler( 1990)
;Spur, G. ;Li, R. ;Lenz, E. ;Shpitalni, M. ;Fischer, A.Krause, F.-L.Modern applications associated with manufacturing can be handled better if multirepresentation based geometrical modelers are used. The integration of several representation schemes has been the aim of a joint project carried out simultaneously in Berlin (IWF) and Haifa (Technion). A geometrical modeler which supports Constructive Solid Geometry, Boundary representation, Octree encoding and Switching Function based representation has been developed. The Compac (Boundary rep) has been selected as the host for the system. An improved input based on CSG has been added. The paper is concerned with the structure of the integrated system and the conversion from one representation method to the another. -
