A method, an apparatus and a computer program product for volumetric video encoding and decoding

A method, comprising:

• receiving a video presentation frame, wherein the video presentation represents a three-dimensional data in the form of mesh data;
• separating from the mesh data information on vertices, wherein the information comprises at least connectivity data defining connections between vertices;
• determining parameters relating to said connectivity data;
• encoding the parameters into a first bitstream as a video component;
• and
• storing the encoded first bitstream for transmission to a rendering apparatus.

A method, comprising:

• receiving a compressed bitstream relating to a video presentation;
• decoding, from the received bitstream, parameters relating to a connectivity data, wherein the connectivity data defines connections between vertices;
• and
• using the connectivity data to reconstruct mesh data representing a three-dimensional data for the video presentation.

An apparatus comprising at least one processor, and a memory including a computer program code, wherein the memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:

• receive a video presentation frame, wherein the video presentation represents a three-dimensional data in the form of mesh data;
• separate from the mesh data information on vertices, wherein the information comprises at least connectivity data defining connections between vertices;
• determine parameters relating to said connectivity data;
• encode the parameters into a first bitstream as a video component;
• and
• store the encoded first bitstream for transmission to a rendering apparatus.
