On sub-division of mesh sequences

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;
• and
• decoding code configured to cause the at least one processor to decode the encoded volumetric data based on displacement vectors of vertices of the mesh,
• wherein the displacement vectors are based on a square root of three subdivision in which faces of the mesh are iteratively subdivided in a manner in which a number of subdivided faces resulting from subdividing the mesh in an iteration is less than four times a number of faces from before subdividing the mesh in the iteration.

A non-transitory computer readable medium storing a program causing a computer to:

• obtain, from a bitstream, a mesh representing an encoded volumetric data of at least one three-dimensional (3D) visual content;
• and
• decode the encoded volumetric data based on displacement vectors of vertices of the mesh,
• wherein the displacement vectors are based on a square root of three subdivision in which faces of the mesh are iteratively subdivided in a manner in which a number of subdivided faces resulting from subdividing the mesh in an iteration is less than four times a number of faces from before subdividing the mesh in the iteration.
