Extraction of ridges-valleys for feature-preserving simplification of polygonal models

Abstract

We propose a new method for simplifying polygonal models while retaining salient features. We extract ridge and valley features defined by means of curvature derivatives on the model surface. We combine this extraction with a simplification technique so as to construct coarse models with features preserved. Experimental results have better quality and smaller geometric error than these of previous method. © Springer-Verlag Berlin Heidelberg 2006.
