Claim 8:
9. The method according to claim 7, wherein after the Level of Detail (LOD) partitioning and lifting transform are performed based on the residual of the encoding point, the method further comprises:
signalling the first model parameter and the second model parameter in an attribute bitstream;
wherein the signalling the first model parameter and the second model parameter in the attribute bitstream comprises:
quantizing the first model parameter and the second model parameter to obtain a quantized first model parameter and a quantized second model parameter; and
signalling the quantized first model parameter and the quantized second model parameter in the attribute bitstream;
or, wherein the signalling the first model parameter and the second model parameter in the attribute bitstream comprises:
signalling the first model parameter and the second model parameter corresponding to a first spatial block of the at least one spatial block in the attribute bitstream; and
calculating values of residuals of model parameters of remaining spatial blocks with respect to a previous spatial block in the at least one spatial block, and signalling the values of the residuals of the model parameters in the attribute bitstream in turn, wherein the at least one spatial block comprises the first spatial block and the remaining spatial blocks.
