FIELD: data coding.
SUBSTANCE: invention relates to the field of data coding. The transform coefficients associated with the point cloud data are decomposed into set index values and symbol index values, where the symbol index value specifies the location of the transform coefficient in the set. The decomposed transform coefficients are divided into one or more sets based on the set index values and the symbol index values. The index values of the divided transform coefficient sets are entropy encoded, and the symbol index values of the divided transform coefficients are bypass encoded. The point cloud data is compressed based on entropy-encoded set index values and bypass-encoded symbol index values.
EFFECT: enabling lossless compression of point clouds in the context of dynamic rendering.
