Abstract
In some examples, an apparatus for mesh coding includes processing circuitry. The processing circuitry receives a data structure for a mesh frame with polygons representing a surface of an object. The data structure for the mesh frame includes a UV atlas that associates vertices of the mesh frame to UV coordinates in the UV atlas. The processing circuitry determines respective sampling rates for regions of the mesh frame according to respective characteristics of the regions of the mesh frame and applies, on the UV atlas, the respective sampling rates for the regions of the mesh frame to determine sampling positions on the UV atlas. The processing circuitry generates one or more sampled two dimensional (2D) maps for the mesh frame according to the sampling positions on the UV atlas, and encodes the one or more sampled 2D maps into a bitstream.
