Claim 9:
10. An apparatus, comprising processing circuitry configured to:
decode an initial map in two-dimension from a bitstream carrying a three dimensional (3D) mesh frame;
determine at least two sampling rates associated with different portions of the initial map;
obtain a recovered map based on the initial map and the at least two sampling rates associated with the different portions of the initial map, a first portion of the initial map being recovered based on a first sampling rate of the at least two sampling rates that is associated with the first portion, and a second portion of the initial map being recovered based on a second sampling rate of the at least two sampling rates that is associated with the second portion; and
reconstruct the 3D mesh frame based on the recovered map.
