Similarly to LEAN mapping, it employs two mipmapped texture maps, which store the first two moments of the displacement gradients. During rendering, the projection of this data over a pixel is used to compute a noncentered anisotropic Beckmann distribution using only simple, linear filtering operations. The distribution is then injected in a new, physically based, rough surface microfacet BRDF model, that includes masking and shadowing effects for both diffuse and specular reflection under directional, point, and environment lighting. Furthermore, our method is compatible with animation and deformation, making it extremely general and flexible. Combined with an adaptive meshing scheme, LEADR mapping provides the very first seamless and hardware-accelerated multi-resolution representation for surfaces. In order to demonstrate its effectiveness, we render highly detailed production models in real time on a commodity GPU, with quality matching supersampled ground-truth images.<\/jats:p>","DOI":"10.1145\/2508363.2508422","type":"journal-article","created":{"date-parts":[[2013,11,6]],"date-time":"2013-11-06T14:09:19Z","timestamp":1383746959000},"page":"1-11","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":69,"title":["Linear efficient antialiased displacement and reflectance mapping"],"prefix":"10.1145","volume":"32","author":[{"given":"Jonathan","family":"Dupuy","sequence":"first","affiliation":[{"name":"Universit\u00e9 de Montr\u00e9al and LIRIS, Universit\u00e9 Lyon 1"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"Heitz","sequence":"additional","affiliation":[{"name":"INRIA\/LJK and Universit\u00e9 de Montr\u00e9al"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Claude","family":"Iehl","sequence":"additional","affiliation":[{"name":"LIRIS, Universit\u00e9 Lyon 1"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Poulin","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Montr\u00e9al"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabrice","family":"Neyret","sequence":"additional","affiliation":[{"name":"INRIA\/LJK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victor","family":"Ostromoukhov","sequence":"additional","affiliation":[{"name":"LIRIS, Universit\u00e9 Lyon 1"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2013,11]]},"reference":[{"key":"e_1_2_2_1_1","volume-title":"Proc.
