Zusammenfassung:	Methods and apparatuses for encoding or decoding animated textured meshes are provided wherein a texture map is encoded that comprises a regular grid of tiles, wherein each tile comprises texture data associated to a patch projected onto the tile, said patch belonging to partitioning of a surface of the texture mesh. According to an embodiment, the partitioning of the surface of the textured mesh is obtained by subdividing the surface of the mesh into a set of regular patches. According to an embodiment, encoding the texture map comprises arranging the tiles of the texture map based on an inter-tile transition cost. According to another embodiment, encoding the texture map comprises arranging the tiles of the texture map based on a distortion cost between the texture map of a reference frame and the texture map of the current frame.
