Claim One:
1. An adaptive rendering apparatus using a hierarchical structure in a 3D image, the adaptive rendering apparatus comprising: a cell data provision unit to divide 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 to generate a 3D rendered image by arranging the cell data output from the cell data provision unit according to the hierarchical structure, wherein a lattice cell belonging to a particular level in the hierarchical structure is divided into a plurality of lattice cells belonging to a level directly below the particular level, and each of the lattice cells in the level directly below the particular level is smaller than the lattice cell of the particular level.
