摘要:
A method and apparatus for encoding and decoding three-dimensional mesh information are provided. The method and apparatus separately encode/decode order information of elements, such as vertices and faces, of a three-dimensional mesh model (original model) in consideration of a change in an element order during encoding three-dimensional mesh information for the original model. The method for encoding three-dimensional mesh information includes the steps of: encoding the three-dimensional mesh information and outputting an encoded bit-stream; calculating order information of at least one element in an original model contained in the three-dimensional mesh information; encoding the element order information; and generating packets of the encoded bit-stream, wherein the encoded element order information is inserted into the packet.

A method and apparatus for encoding and decoding three dimensional (3D) mesh information, especially, for outputting data in a decoding process with the number of digits of original data are disclosed. One embodiment of the present invention comprises 3DMC mesh data encoding at a transmitting end for counting the number of digits of original data and generating a 3DMC packet including an encoded original data and the digit number, transmitting the 3DMC packet to a receiving end, and 3DMC mesh data decoding at the receiving end for reconstructing and outputting the encoded original data based on the number of digits. According to one embodiment of the invention, the fidelity of data reconstruction is increased.
