Claim 21:
22. A device for encoding a point cloud, the device comprising:
a memory to store point cloud data representing the point cloud; and
one or more processors coupled to the memory and implemented in circuitry, the one or more processors configured to:
based on a maximum difference value being less than a threshold, determine a predictor index for a current point of the point cloud that indicates a predictor in a predictor list, wherein predictors in the predictor list are based on attribute values of one or more neighbor points;
generate a first jointly coded value based on (i) a first residual value for attribute values of the current point and (ii) the predictor index;
generate a second jointly coded value based on (i) a second residual value for the attribute values of the current point and (ii) the predictor index; and
signal the first and second jointly coded values.
