Abstract
Embodiments of the present disclosure provide a method for point cloud coding. In the method, for a conversion between a current coding unit of a point cloud sequence and a bitstream of the point cloud sequence, at least one coded geometry coordinate of the current coding unit is determined. A de-quantization is applied to the at least one coded geometry coordinate. An attribute coding is applied to the at least one de-quantized geometry coordinate of the current coding unit. The conversion is performed based on the attribute coding.
