Abstract

See full text

A method for coding three-dimensional (3D) data, and more particularly for coding geometry data included in the 3D data. The method includes: generating a bounding box including a vertex of the 3D data based on information included in the geometry data; dividing the bounding box into a plurality of partitions having an equal size; identifying a number of vertices included in each divided partition; appointing a divided partition as a leaf cell based on the identified number of vertices; and coding the geometry data using information on the dividing of the bounding box, information on vertices included in each divided partition, and information indicating the position of a vertex included in the leaf cell, when a divided partition is subdivided.
