Geometry compression is an effective way to distribute high-volume geometry data within limited bandwidth and storage capacity. In this paper, a new time-varying 3D geometry compression method based on 4D lifted wavelet transform is presented. In this hybrid approach, geometric information and animation are compressed based volume grid values. Isosurfaces are reconst-ructed from decompressed grid values. With rescaling and integer-to-integer lifting, compression ratio is significantly increased without compromising quality of surfaces.
