An Extremely Inexpensive Multisampling Scheme

[Rapport]

We present a new sampling scheme for low-cost multisampling rasterization. The scheme builds upon sample sharing and the N-rooks sample scheme, and it achieves at most two shades in between fully outside and fully inside. Also, the slightly irregular pattern helps disguising aliasing effects. A simple visual evaluation shows that our new scheme gives similar quality to that of the Quincunx scheme. More importantly, our scheme uses only 1.25 samples on average per pixel, while Quincunx and FLIPQUAD uses 2 samples. As a consequence, our new scheme uses 62:5 percent of the memory and memory bandwidth as compared to Quincunx and FLIPQUAD.
