Abstract

Polygonal meshes are the most popular representation scheme for 3D surfaces in computer graphics. Polygonal meshes usually have topological and/or geometric noises during their scanning and collection steps. Many geometric computing and manipulation operations need to be performed on clean meshes. Therefore, topological noises on polygonal meshes need to be removed in a preprocessing step, which is called topology denoise. We classify a few popular topology denoise technologies and analyze their properties.
