ABSTRACT
Despite its other advantages, one of the major objections to raster graphics has been the poor image quality and aliasing effects caused by discrete sampling. These effects include “jaggies” or stair-stepping, crawling, line breakup, and scintillation. Several solutions have been proposed in the literature, however, most suffer severe drawbacks and are only partially successful at eliminating aliasing effects. One solution, area anti-aliasing, is not only effective, it produces results comparable to higher resolution systems. Using widely available data on human visual response, it is shown how this technique actually increases the perceived resolution of a display beyond the hardware resolution by factors of up to 16X. The requirements of such a system are discussed, as well as some of the problems encountered.

Surface based anti-aliasing
I3D '12: Proceedings of the ACM SIGGRAPH Symposium on Interactive 3D Graphics and GamesWe present surface based anti-aliasing (SBAA), a new approach to real-time anti-aliasing for deferred renderers that improves the performance and lowers the memory requirements for anti-aliasing methods that sample sub-pixel visibility. We introduce a ...
Aggregate G-buffer anti-aliasing
i3D '15: Proceedings of the 19th Symposium on Interactive 3D Graphics and GamesWe present Aggregate G-Buffer Anti-Aliasing (AGAA), a new technique for efficient anti-aliased deferred rendering of complex geometry using modern graphics hardware. In geometrically complex situations, where many surfaces intersect a pixel, current ...
