1. A method comprising:
generating at least one additional 3D sample to a reconstructed point cloud frame from a layer storing depth values of 3D samples of the reconstructed point cloud frame using a Point Local Reconstruction mode indicated by a first syntax element, the Point Local Reconstruction mode comprising at least one parameter defining the Point Local Reconstruction mode,
signaling in a bitstream a second syntax element per patch of the point cloud frame, the second syntax element indicating whether the first syntax element is signaled once per patch and the same first syntax element is used for all blocks of the patch or whether the first syntax element is signaled for each block of the patch,
signaling in the bitstream the first syntax element depending on the second syntax element.
