Here is what I saw at Sharkyextreme: "Using a new technique dubbed HRAA, NVIDIA claims that they can achieve better performance than super-sampling with comparable quality. A "reconstruction filter" uses data from neighboring pixels to compute the final output of any given pixel. The sampling pattern used by the reconstruction filter is called Quincunx and, according to NVIDA, offers quality rivaling traditional four-sample super-sampling while incurring the performance hit of two-sample super-sampling." http://www.sharkyextreme.com/hardware/articles/nvidia_geforce3_preview/6.sht ml To me, this says Quincunx is the HRAA, which is the MSAA. After seeing that, I checked Nvidia's site and downloaded the HRAA brief (PDF). It backs up the statement made at Shary's by having this: "GeForce3 has new technology for graphics hardware antialiasing in the form of multisampling using a new sampling pattern. The locations of the sample points for multisampling enable the use of a "reconstruction filter" that uses data from neighboring pixels to compute the final pixel color. This increases the total amount of work, and therefore slows down the frame rate marginally, but it delivers much higher quality as a reward. This new sampling pattern is called Quincunx, after the name of the pattern of the five dots on the "5" sided of a 6-sided die." http://www.nvidia.com/Pages.nsf/Lookup/HRAA/$file/HRAA.pdf "david woolfe" <dwoolfe@home.com> wrote in message news:3aa30361.27887413@news... > Well, this article strongly implies that all GF3 FSAA will use > multisampling, with three options: 2x, 4x, and "quincunx."
