From solids to particle-based models

This paper addresses the issue of generating mathematical models of flexible objects suitable for NRM simulation. These models should contain proper information not only on the objects geometry, but also on the physical properties of the material they are made of. This paper mainly addresses the geometrical issues of generating particle-based models of flexible objects, but basic methods for determining the material characterization in some special cases are also discussed. The ongoing research work performed by the authors and the related results are presented.
