High-Quality Antialiased Rasterization

Finely detailed 3D geometry can show significant aliasing artifacts if rendered using native hardware multisampling, because multisampling is currently limited to one-pixel box filtering and low sampling rates. This chapter describes a tiled supersampling technique for rendering images of arbitrary resolution with arbitrarily wide user-defined filters and high sampling rates. The code presented here is used in the Gelato film renderer to produce images of uncompromising quality using the GPU.
