Method, apparatus, and non-transitory computer-readable recording medium for streaming 3d objects

A method for reproducing a 3D object on a client, the 3D object being present on a server, the method comprising:

• receiving from the server, an encoded stream including color information, alpha information and geometry information of the 3D object;
• decoding the encoded stream and extracting the color information, the alpha information and the geometry information from the decoded stream;
• reproducing a shape of the 3D object based on the geometry information;
• and
• projecting information on the reproduced shape of the 3D object to reconstruct the 3D object, the information resulting from combining the color information and the alpha information.

A server comprising at least one processor and a memory, wherein

• the at least one processor executes instructions stored in the memory, to
• extract color information, alpha information and geometry information from a 3D object on the server;
• simplify the geometry information;
• and
• encode a stream including the color information, the color information, the alpha information and the simplified geometry information and send the encoded stream from the server to a client.
