Abstract:
The invention relates to the encoding and decoding of texture mapping data of a textured 3D object. A 3D object is usually represented by connectivity, geometry and property data. The texture data, belonging to the property data, include a texture image; a texture coordinates table having entries, each entry defining coordinates in the texture image; and texture indexes associating each vertex of a polygon in the 3D object with an entry in the texture coordinates table. The present invention proposes to search for and delete entry duplicates from the texture coordinates table. To reduce encoding complexity, the search and deletion are based on the connectivity data. This is to exploit redundancies between the mesh connectivity for the polygons within the 3D object and the texture connectivity for the texture polygons within the texture image.

Claim (Index 14):
A method for decoding a bitstream into a textured three-dimensional mesh model composed of polygons between connected vertices, the method comprising the following steps:\n obtaining, from the bitstream, connectivity data describing the connectivity between the vertices in the textured 3D mesh model, obtaining, based on the bitstream, texture data including:\n a texture image, \n a texture coordinates table having entries, each entry defining a set of coordinates in the texture image, and \n texture coordinates indexes associating each vertex of a polygon in the textured 3D mesh model with an entry in the texture coordinates table; and \n rendering the textured 3D mesh model using the obtained connectivity and texture data, wherein obtaining, from the bitstream, texture coordinates indexes includes: decoding a texture flagging table from the bitstream, and successively considering each vertex of the textured 3D mesh model according to a connectivity order inferred from the obtained connectivity data to build a texture coordinates indexes table, wherein for each vertex currently considered, the polygons that shares the vertex currently considered as a polygon vertex are determined, and one or more flags associated with one or more polygons of the determined polygons are read from the decoded texture flagging table, and an index associated with the vertex currently considered in each of the one or more polygons is set in the texture coordinates indexes table based on the respective read flag.
