1. One or more non-transitory computer-readable storage media storing program instructions that, when executed on or across one or more computing devices, cause the one or more computing devices to:
for respective ones of a plurality of points included in three-dimensional (3D) visual content:
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; and
