From Geometric Modeling to Shape Modeling

IFIP Working Group 5.2 has organized a series of workshops aimed at presenting and discussing current issues and future perspectives of geometric modelling in the CAD environment. This text comprises the proceedings of the seventh GEO workshop, which was sponsored by the International Federation for Information Processing (IFIP) and held in Parma, Italy in October 2000. The workshop looked at paradigms for CAD, including the evolution of geometric-centric CAD systems, modeling of non-rigid materials, shape modeling, geometric modelling and virtual prototyping, and methods of interaction with geometric models. The 17 included papers provide an overview of the evolution of geometric centric modelling into shape modelling. Also included is an invited speaker paper, which discusses the foundation of the next generation of CAD systems, where shape and function enhance geometric descriptions.
