A system for full-scene anti-aliasing and stereo three-dimensional display control. The system includes a receiving buffer, a geometry offset generator, a rendering engine, and a blending engine. The receiving buffer receives a geometry, and the geometry offset generator receives stereo parameters and FSAA parameters, calculates first and second stereo offsets according to the stereo parameters, and calculates first and second FSAA offsets according to the FSAA parameters. The rendering engine combines the first and second stereo offsets with the first FSAA offset respectively to obtain first and second new offsets, combines the first and second stereo offsets with the second FSAA offset respectively to obtain third and fourth new offsets, and re-renders the geometry according to the first, second, third, and fourth new offsets respectively, so as to obtain first, second, third, and fourth new geometry. The blending engine blends the first and third new geometry to obtain a first display geometry, and blends the second and fourth new geometry to obtain a second display geometry.
