Similar to previous work, we use a deep-framebuffer shaded on the GPU to achieve interactive performance. Our first contribution is to generate the deep-framebuffer and corresponding shaders automatically through data-flow analysis and compilation of the original scene. Cache compression reduces automatically-generated deep-framebuffers to reasonable size for complex production scenes and shaders. We also propose a new structure, the\n            <jats:italic>indirect framebuffer<\/jats:italic>\n            , that decouples shading samples from final pixels and allows a deep-framebuffer to handle antialiasing, motion blur and transparency efficiently. Progressive refinement enables fast feedback at coarser resolution. We demonstrate our approach in real-world production.\n          <\/jats:p>","DOI":"10.1145\/1276377.1276409","type":"journal-article","created":{"date-parts":[[2007,9,14]],"date-time":"2007-09-14T13:44:55Z","timestamp":1189777495000},"page":"25","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":25,"title":["The lightspeed automatic interactive lighting preview system"],"prefix":"10.1145","volume":"26","author":[{"given":"Jonathan","family":"Ragan-Kelley","sequence":"first","affiliation":[{"name":"MIT CSAIL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charlie","family":"Kilpatrick","sequence":"additional","affiliation":[{"name":"Industrial Light &amp; Magic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian W.","family":"Smith","sequence":"additional","affiliation":[{"name":"Industrial Light &amp; Magic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Doug","family":"Epps","sequence":"additional","affiliation":[{"name":"Tippett Studio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Green","sequence":"additional","affiliation":[{"name":"MIT CSAIL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christophe","family":"Hery","sequence":"additional","affiliation":[{"name":"Industrial Light &amp; Magic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fr\u00e9do","family":"Durand","sequence":"additional","affiliation":[{"name":"MIT CSAIL"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2007,7,29]]},"reference":[{"unstructured":"Alias 1999.
