description The present disclosure relates to an information processing apparatus and method that enable attribute data to be decoded more reliably.Nearby point search for setting a reference point to be referred to when deriving a prediction value of attribute data of a processing target node is executed only for a node that is decoded earlier than the processing target node at the time of decoding among nodes of a tree structure in which attribute data of each point of a point cloud expressing an object having a three-dimensional shape as a set of points is a node and slices serving as node groups that can be encoded independently of each other are formed. The present disclosure can be applied to, for example, an information processing apparatus, an encoding apparatus, a decoding apparatus, an electronic device, an information processing method, or a program.
