3D image processing method and apparatus for enabling efficient retrieval of neighboring point

Abstract

Disclosed are data storing and processing methods or apparatuses which may efficiently perform a process of retrieving neighboring points between points stored in a leaf cell in a point-based 3D data expressing method. A computer-readable recording medium having stored thereon instructions for implementing a method of three-Dimensional (3D) data processing, the instructions including an instruction set of connecting each of a plurality of points with a leaf cell of a spatial tree structure; an instruction set of assigning a ball to correspond to each of the plurality of points; and an instruction set of connecting the ball with a leaf cell intersecting the ball.

Dependencies are inferred from the claim text.
