Abstract
A 3D graphic accelerator and a method for processing a graphic acceleration using the same is provided in which the inputted primitives are geometrically processed, and existence of any transparent primitives or dominance/rarity of opaque primitives is determined among the geometrically processed primitives. The primitives are rendered in an object-order style and an image-order style in accordance with the determination. The information on the rendered primitives is stored in a corresponding frame buffer and a bucket, and the rendered primitives are display-refreshed. Thus, the 3D graphic accelerator with order- independent transparency and high performance is obtained.
