Abstract: PURPOSE: A three-dimensional texture based volume graphic structure using a visibility-ordered division rendering algorithm and a method therefor are provided to prevent lowering of performance and reduce the size of a required bandwidth. CONSTITUTION: A volume divider(20) decides the size of division volume regions and an order for processing through view point plane of one volume data, and the size and position information of volume information, and generates a three-dimensional texture map. A section generator(40) generates sections of the divided regions by receiving position information of the divided regions and the number of sections per divided region. A geometry operation unit(50) geometrically operates the sections. A three-dimensional texture mapping(60) generates the sections into preliminarily generated three-dimensional texture through the volume information of the corresponding region. An alpha blender(70) alpha-blends the sections one by one. A pixel cache(80) reads the corresponding section information from a frame memory(100) storing the blended section information by the section units to store the read section information, and is used as a cache between the alpha blender and the frame memory.
