Abstract
A system, method and medium renders an object into a 3-dimensional (3D) graphic image. The rendering system includes a polygon processing unit to calculate a plurality of LOD values of a plurality of fragments corresponding to a plurality of vertices of a predetermined polygon, among a plurality of fragments constructing the predetermined polygon, a span conversion unit to interpolate a plurality of LOD values of remaining fragments apart from the plurality of fragments corresponding to the vertices of the predetermined polygon, using the calculated LOD values, and a texture mapping unit to map one of a plurality of textures with various resolutions to a corresponding fragment of the fragments constructing the predetermined polygon, on the basis of the LOD values interpolated by the span conversion unit.
