Reverse subdivision multiresolution for polygonal silhouette error correction

Abstract

This paper presents a method for automatic removal of artifacts that appear in silhouettes extracted from polygonal meshes due to the discrete nature of meshes and numerical instabilities. The approach works in object space on curves made by chaining silhouette edges and uses multiresolution techniques based on a reverse subdivision method. These artifact-free curves are then rendered in object-space as weighted 3D triangle-ribbon strips.
