METHOD FOR ENCODING AND DECODING THREE-DIMENSIONAL MESH INFORMATION AND APPARATUS THEREOF

摘要

PURPOSE: A method for encoding and decoding three-dimensional mesh information and an apparatus thereof are provided to more efficiently process animation by including information related to the defined DEF name in the apparatus for coding 3D mesh. CONSTITUTION: A method for encoding three-dimensional mesh information includes the steps of forming a plurality of partition fields including start and identification information, and forming a name field including DEF names(501) of dependent nodes within an IFS(Indexed Face Set) and combining the name field with the plurality of partition fields, thereby generating mesh information. A method for decoding three-dimensional mesh information includes the steps of confirming whether input information is a start code of an MOBL(Mesh Object Base Layer) or a start code(502) of the DEF names, confirming partition according to the start code of the MOBL and a peculiar identifier before processing the partition in the case of the start code of the MOBL, analyzing the DEF names of the dependent nodes according to the start code and the name information of the dependent nodes in the case of the start code of the DEF name.
