Subpixel reconstruction antialiasing for deferred shading
Matthäus G. Chajdas, Morgan McGuire, David P. Luebke · 2011
Subpixel Reconstruction Antialiasing (SRAA) combines singlepixel (1x) shading with subpixel visibility to create antialiased images without increasing the shading cost. SRAA targets deferred-shading renderers, which cannot use multisample antialiasing.
