Abstract: Systems and methods for a point cloud decoder including a processor to decode each block in a set of blocks from a point cloud, so as to obtain a decoded point cloud. Wherein each block includes a set of points, such that for each block the processor is to decode a set of prediction residuals from a compressed bitstream. Use a predetermined location in the block, and compute for each prediction residual in the set of prediction residuals, a position of a point by adding the prediction residual to the predetermined location, so as to obtain a set of decoded points for the block. Wherein the decoded points for the blocks in the set of blocks represent the decoded point cloud.
