3D Mesh Compression Using Fixed Spectral Bases

Zachi Karni and Craig Gotsman

Abstract

We show how to use fixed bases for efficient spectral compression of 3D meshes. In contrast with compres-sion using variable bases, this permits efficient decoding of the mesh. The coding procedure involves efficient mesh augmentation and generation of a neighborhood-preserving mapping between the vertices of a 3D mesh with arbitrary connectivity and those of a 6-regular mesh.
