11. Problems Undersampling: Triangles thinner than a pixel Long, thin triangles - eg a very long quad Foreshortened triangles near silhouettes of organic objects, such as characters Subpixel gaps No distance-to-edge information: Interpenetrating geometry Shadow edges Texture aliasing

12. Other uses for the DEAA buffer Simulate transparency with alpha-to-coverage Better alpha-tested edges, eg foliage
