Abstract
An apparatus for mesh decoding is provided. The apparatus includes processing circuitry. The processing circuitry is configured to receive a bitstream that includes displacement information and base mesh information of a mesh in a current mesh frame. The displacement information indicates a plurality of displacements associated with a base mesh and the mesh. The base mesh includes a subset of a plurality of vertices of the mesh. The processing circuitry is configured to determine a last non-zero quantized wavelet coefficient of a plurality of non-zero quantized wavelet coefficients in a coefficient array associated with the plurality of displacements based on index information included in the bitstream. The processing circuitry is configured to reconstruct the mesh based on the plurality of displacements indicated by the plurality of non-zero quantized wavelet coefficients.
