Optimization of surface mesh quality with feature preserving

Abstract

In this paper, we present a novel technique to improve quality of triangular surface meshes while maintaining all essential surface characteristics. In contrast to previous methods we do not constrain node movement to the underlying discrete surface. Instead our approach allows keeping resultant mesh very close to the smooth surface approximated by the original mesh. Proposed method is explicit, that is we do not need any parameterization of the original mesh. All operations are performed directly on the surface. As a result our technique is robust and runs at interactive speeds.
