Line 31:

Pixel decompositions divide the pixels of the final view evenly, either by dividing full pixels or sub-pixels. The first 'squeezes' the view frustum, while the second renders the same scene with slightly modified camera positions for full-screen anti-aliasing or depth-of-field effects. Pixel decompositions do composite the pixels side-by-side, while sub-pixel decompositions blend all sub-pixels to compute the final pixel.

In contrast to sort-first, no sorting of rendered primitives takes place since all rendering resources render more or less the same view. Pixel decompositions are inherently load-balanced, and are ideal for purely fill-limited applications such as raytracing and 3D [[volume rendering]].
