Abstract
Apparatuses and methods are disclosed for progressively encoding a mesh. Techniques disclosed include obtaining displacement data representative of a spatial difference between a base mesh and the mesh to be encoded, transforming the displacement data into wavelet coefficients, computed at multiple resolution levels, and then zerotree encoding the wavelet coefficients in a traversal order according to a zerotree hierarchy, generating a zerotree bitstream of coded displacement data. Further apparatuses and methods are disclosed for progressively decoding the mesh. Techniques disclosed include obtaining the zerotree bitstream that codes the displacement data, zerotree decoding the wavelet coefficients from the bitstream, and inverse transforming the decoded wavelet coefficients into decoded displacement data.
