Claim 19:
20. The device of claim 14, wherein the memory further stores additional program instructions that, when executed on or across the one or more processors, cause the one or more processors to:
receive 3D visual content to be compressed; and
for respective ones of a plurality of points included in the 3D visual content to be compressed:
identify a set of neighboring points;
determine a predicted attribute value for the respective point based, at least in part, on predicted or assigned attributes values for the neighboring points and respective distances between the respective point and respective ones of the neighboring points; and
determine an attribute correction value for the point based, at least in part, on comparing the predicted attribute value for the respective point to attribute information for the point included in the 3D visual content to be compressed; and

encode compressed attribute information for the 3D visual content to be compressed, wherein the compressed attribute information for the 3D visual content to be compressed comprises:
data indicating, for the respective ones of the points, the determined attribute correction values.
