Abstract:
Many 3D models used in engineering, scientific, and visualization
applications are represented by an irregular mesh of bounding
quadrilaterals. We propose a scheme for compressing the connectivity of
irregular quadrilateral meshes in 0.26-1.7 bits/quad, a 25-45% savings
over randomly splitting quads into triangles and applying triangle mesh
compression. Our approach is an extension of the Edgebreaker compression
approach and of the Wrap&Zip decompression technique.
