3D mesh coding/decoding method

摘要: A progressive coding and decoding method of three-dimensional (3D) mesh data used in the fields motion picture experts group-4 synthetic natural hybrid (MPEG-4 SNHC), virtual reality modelling language (VRML) like. In transmitting 3D objects composed data, it is very important to progressively restore transmitted as well effectively code data. restoration, event that a transmission error generated, partial restoration allowed. Thus, possible minimize amount be again. The which resistant such errors can applied wireless communications or low rate communications. method, connectivity, geometry photometry necessary for are constructed then coded/decoded, thereby providing resilience against errors.
