1. A non-transitory computer-readable medium storing program instructions that, when executed by one or more processors, cause the one or more processors to:
receive a bit stream comprising information for compressed three-dimensional visual content;
determine, using inter-component prediction, attribute values to be used in reconstructing the three-dimensional visual content, wherein to determine the attribute values using the inter-component prediction, the program instructions when executed by the one or more processors, cause the one or more processors to:
predict an attribute component value for a first attribute component assigned to a given point of the three-dimensional visual content; and
predict a second attribute component value for a second attribute component assigned to the same given point based, at least in part, on the attribute component value predicted for the first attribute component assigned to the given point.
