A three-dimensional graphics system is provided. The three-dimensional graphics system rasterizes each of a plurality of polygons generated from vertexes in an order adapted to characteristics of each polygon. The three-dimensional graphics system includes a rasterization engine including a polygon setup unit receiving the vertexes and generating the polygons and rasterization information for each polygon, and a rasterizer rasterizing pixels using the rasterization information received from the polygon setup unit in an order adapted to the characteristics of each polygon. Accordingly, the coherence of the pixels is increased and the hit ratio of cache memory is thus increased. As a result, the performance of the three-dimensional graphics system is improved. With the increase of the hit ratio of the cache memory, buss traffic in the system is reduced and power consumption is thus reduced. |
