The Reverse Engineering book presented here is a compilation of the result of a workshop on reverse engineering in which: - the newest theoretical results and surface reepresentation for a given set of points were presented - some of the most important CAD-System vendors (EDS-Unigraphics, Holometric Technologies, IBM/ Dassault, ICEM, Imageware, Matra Datavision, SDRC, Tebis) presented their methods and tools for problems in Reverse Engineering - structural aspects in Reverse Engineering were discussed -Theoretical presentations and CAD systems sessions can be compared aand evaluated using some benchmarks.
