Patch creation and signaling for v3c dynamic mesh compression

A method comprising:

• receiving a parameterized mesh, the mesh defining a shape and attributes of an object in three-dimensional space;
• compressing the mesh to generate a two-dimensional patch of the mesh;
• and
• signaling at least one of:
• projection plane changes within the patch to support patches wrapping around a three-dimensional model;
• separation of attribute and geometry patch level of detail scaling to support at least one high resolution attribute patch alongside at least one lower resolution geometry patch, reflecting at least one feature of at least one lower vertex count mesh;
• or
• separation of attribute and geometry patch orientation for image packing.

A method comprising:

• receiving a compressed parameterized mesh, the mesh defining a shape and attributes of an object in three-dimensional space;
• decompressing the mesh from a two-dimensional patch of the mesh;
• and
• receiving signaling of at least one of:
• projection plane changes within the patch to support patches wrapping around a three-dimensional model;
• separation of attribute and geometry patch level of detail scaling to support at least one high resolution attribute patch alongside at least one lower resolution geometry patch, reflecting at least one feature of at least one lower vertex count mesh;
• or
• separation of attribute and geometry patch orientation for image packing.

An apparatus comprising:

• at least one processor;
• and
• at least one non-transitory memory including computer program code;
• wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
• receive a parameterized mesh, the mesh defining a shape and attributes of an object in three-dimensional space;
• compress the mesh to generate a two-dimensional patch of the mesh;
• and
• signal at least one of:
• projection plane changes within the patch to support patches wrapping around a three-dimensional model;
• separation of attribute and geometry patch level of detail scaling to support at least one high resolution attribute patch alongside at least one lower resolution geometry patch, reflecting at least one feature of at least one lower vertex count mesh;
