Abstract
We 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 novel way of
decoupling visibility determination from shading that, compared to
previous multi-sampling based approaches, significantly reduces the number
of samples stored and shaded per pixel. Unlike post-process anti-aliasing techniques used
in conjunction with deferred renderers, SBAA correctly resolves
visibility of sub-pixel features, minimizing spatial and temporal
artifacts.
