ADAPTIVE RENDERING APPARATUS BASED ON HIERARCHICAL STRUCTURE IN 3D IMAGE, APPARATUS AND METHOD FOR GENERATING CELL DATA, RENDERING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM STORING COMPUTER PROGRAM FOR EXECUTING THESE METHODS

摘要

PROBLEM TO BE SOLVED: To provide an adaptive rendering apparatus and method using a hierarchical structure in a 3D image, and a computer-readable recording medium storing a computer program for executing the adaptive rendering method. SOLUTION: The adaptive rendering apparatus includes a cell data provision unit 110, which divides an original 3D image into a plurality of lattice cells that are connected to one another in a hierarchical structure according to predetermined rendering conditions and outputs a plurality of cell data of an area of the original 3D image corresponding to the lattice cells, and a rendered image generation unit 120, which generates 3D rendered image data by arranging a plurality of outputted cell data according to the hierarchical structure. A lattice cell belonging to a particular level is capable of being divided into a plurality of lattice cells belonging to a level directly below the particular level, and the lattice cells are characterized in that the lower the level of the lattice cells, the smaller the size of the lattice cells.
