Abstract
A method and apparatus comprising computer code configured to cause a processor or processors to obtain, from a bitstream, a mesh representing an encoded volumetric data of at least one three-dimensional (3D) visual content; partition a plurality of vertices of the mesh into a plurality of groups; and decode the encoded volumetric data by predicting the vertices in each group of the plurality of groups based on at least one traversal order depending on an reference vertex of the vertices and whether the volumetric data comprises one or more split vertices.

A method for video decoding, the method performed by at least one processor and comprising:
- obtaining, from a bitstream, a mesh representing an encoded volumetric data of at least one three-dimensional (3D) visual content;
- partitioning a plurality of vertices of the mesh into a plurality of groups;
- and
- decoding the encoded volumetric data by predicting the vertices in each group of the plurality of groups based on at least one traversal order depending on a reference vertex of the vertices and whether the volumetric data comprises one or more split vertices.
An apparatus for video decoding, the apparatus comprising:
- at least one memory configured to store computer program code;
- at least one processor configured to access the computer program code and operate as instructed by the computer program code, the computer program code including:
- obtaining code configured to cause the at least one processor to obtain, from a bitstream, a mesh representing an encoded volumetric data of at least one three-dimensional (3D) visual content;
- partitioning code configured to cause the at least one processor to partition a plurality of vertices of the mesh into a plurality of groups;
- and
- decoding code configured to cause the at least one processor to decode encoded volumetric data by predicting the vertices in each group of the plurality of groups based on at least one traversal order depending on a reference vertex of the vertices and whether the volumetric data comprises one or more split vertices.
A non-transitory computer readable medium storing a program causing a computer to:
- obtaining, from a bitstream, a mesh representing an encoded volumetric data of at least one three-dimensional (3D) visual content;
- partitioning a plurality of vertices of the mesh into a plurality of groups;
- and
- decoding the encoded volumetric data by predicting the vertices in each group of the plurality of groups based on at least one traversal order depending on a reference vertex of the vertices and whether the volumetric data comprises one or more split vertices.
