Title:

Feature Sensitive Surface Extraction from Volume Data

Abstract:

The representation of geometric objects based on volumetric data structure has advantages in many geometry processing applications. However, surface based algorithms often need a topological manifold representation where neighborhood information within the surface is explicitly available. Consequently, it is necessary to find effective conversion algorithms to generate explicit surface descriptions for the geometry which is implicitly defined by a volumetric data set. Since volume data is usually sampled on a regular grid with a given step width, we often observe severe alias artifacts at sharp features on the extracted surfaces. In this paper a new technique for surface extraction is presented that performs feature sensitive sampling and thus reduces these alias effects while keeping the simple algorithmic structure of the standard Marching Cubes algorithm.
