# Amortized Supersampling

## One-sentence takeaway

Yang et al. amortize 4×4-quality antialiasing by shading about one new subpixel sample per pixel per frame and reprojecting the rest from a small ring of previous subpixel buffers.

## Why it matters here

This 2009 SIGGRAPH Asia paper is the ancestor of TAA / TSR: Anoptic’s temporal AA stack is the same reuse-plus-reject idea, later dressed with velocity buffers and neighborhood clamps.

## Key ideas

- Maintain several subpixel-offset color (and depth) buffers. Each frame shades a new jittered sample and warps older samples into the current view.
- Reprojection uses depth to reject disocclusions; missing samples are regenerated rather than ghosted.
- Cost is close to 1× shading plus a resolve, with quality they compare to 4×4 stratified supersampling on static or slowly moving content.
- Published as ACM TOG 28(5) with DOI 10.1145/1618452.1618481 (the 10.1145/1661412.1618480 id is the conference-proceedings sibling).
