Mesh Compression Using Coding Units with Different Encoding Parameters

A non-transitory, computer-readable storage medium storing program instructions, that when executed using one or more processors, cause the one or more processors to:

• decode an encoded representation of a mesh, wherein the encoded representation comprises a plurality of coding units and associated encoding parameters for the respective coding units, wherein to decode the encoded representation of the mesh, the program instructions cause the one or more processors to:
• generate a first portion of the mesh by decoding a first coding unit encoded using a first set of encoding parameters;
• generate a second portion of the mesh by decoding a second coding unit encoded using a second set of encoding parameters;
• and
• merge vertices of the first portion and the second portion of the mesh that are located at boundaries of the first portion and the second portion, wherein the merged vertices represent a single vertex in a reconstructed version of the mesh, reconstructed from the encoded representation.

A device, comprising:

• one or more memory storing program instruction;
• and
• one or more processors,
• wherein the program instruction, when executed using the one or more processors cause the one or more processors to:
• encode a mesh using a plurality of coding units that represent portions of the mesh, wherein to encode the mesh using the plurality of coding units, the program instructions, cause the one or more processors to:
• identify vertices of the mesh located at boundaries between respective ones of the coding units;
• and
• adjust one or more encoding parameters used to encode information for the vertices on the boundaries of the coding units such that vertices shared by adjacent coding units are aligned in a reconstructed version of the mesh, reconstructed using an encoded version of the mesh encoded using the coding units.
