Abstract

See full text

A method and an apparatus for generating or decoding a bitstream representing a 3D model are described. The method comprises the steps of: accessing a first quantization parameter indicating the quality of the reconstructed 3D model; determining a second quantization parameter used for encoding or decoding patterns associated with the 3D model as a function of the first quantization parameter; performing the encoding or decoding of a pattern in response to the second quantization parameter; determining a third and a fourth quantization parameters for the transformation information for an instance being represented as a transformation of the pattern as a function of the second quantization parameter; and performing encoding or decoding of the transformation for the instance in response to the third and fourth quantization parameter. A corresponding apparatus, a computer readable storage medium having stored thereon instructions for generating or decoding a bitstream and a computer readable storage medium having stored thereon a bitstream generated according to the method are also provided.
