An Improvement of Connectivity Compression for Triangular Meshes

Abstract

Polygonal meshes have been used as the primary geometric model representation for networked gaming and for complex interactive design in manufacturing. Accurate polygonal mesh approximation of a surface with sharp features requires extremely large number of triangle. The need for succinct representation is not only to reduce storage requirements, but also to consume less network bandwidth and thus reduce the transmission time. In this paper, we propose a new method for compressing the connectivity of triangle meshes homeomorphic to a sphere. In average, it encodes with less than 1.19t bits of any ttriangles mesh. Furthermore, it is suitable for compressing all models and particularly attractive for compressing large object for remote instant access without overhead.
