FIELD: coding technology.
SUBSTANCE: invention relates to point cloud encoding technologies and, in particular, to the compression of point cloud geometry, including a generalization of lossy MPEG/G-RSS compression using a triangular grid and a fast “rate-distortion” optimization scheme (RDO). A method and device containing computer a code are proposed for the processor to execute, obtain a leaf node of point cloud compression data based on geometry (G-PCC), divide the leaf node into a set of cuboids, obtain separate triangular grids for each cuboid and encode a set of flags, respectively, for each of the edges of each cuboid, while the set of flags indicates, if the vertices of individual triangular grids are present on the edges of the mentioned edges.
EFFECT: reduction in the amount of data required to represent the point cloud.
