    摘要: A method of progressively coding/decoding 3-D mesh information, and an apparatus therefor are provided. The progressive 3-D mesh information coding method includes the steps of reconstructing an input 3-D mesh into a plurality of mesh components, coding each of the plurality of mesh components, and multiplexing the plurality of coded mesh components into a compressed bit stream and transmitting the compressed bit stream. The method of progressively decoding the transmitted, compressed bit stream which has been coded by the coding method, includes dividing the transmitted bit stream into a plurality of coded mesh components, decoding each of the plurality of coded mesh components, and reconstructing a 3-D mesh by synthesizing the plurality of decoded mesh components.

    摘要: Provided are encoding and decoding stitching information generated when the 3D mesh model that is the non-manifold or non-orientable model is converted into orientable and manifold models upon encoding the 3D mesh information of the 3D mesh model. The method of encoding 3D mesh information includes the steps of: encoding the 3D mesh information to output an encoded bitstream; encoding stitching information of elements contained in the 3D mesh information, the stitching information having a total number of duplicated original elements and, for each of the duplicated original elements, the duplication number, original-element identification information and duplicated-element identification information; and generating a packet of the bitstream, wherein the encoded stitching information is inserted into the packet.
