'''Parallax occlusion mapping''' (POM) is an enhancement of the [[parallax mapping]] technique. Parallax occlusion mapping is used to [[Procedural generation|procedurally]] create 3D definition in textured surfaces, using a [[displacement map]] (similar to a topography map) instead of through the generation of new geometry.<ref name="Original Document">Brawley, Z., and Tatarchuk, N. 2004. Parallax Occlusion Mapping: Self-Shadowing, Perspective-Correct Bump Mapping Using Reverse Height Map Tracing. In ShaderX3: Advanced Rendering with DirectX and OpenGL, Engel, W., Ed., Charles River Media, pp. 135-154. https://books.google.com/books?id=DgMSb_10l7IC&pg=PA135&dq=parallax+occlusion</ref> This allows developers of [[3D computer graphics|3D]] rendering applications to add 3D complexity in [[Texture mapping|textures]], which correctly change relative to [[Perspective (visual)|perspective]] and with self [[Hidden surface determination|occlusion]] in [[Real-time computer graphics|real time]] ([[self-shadowing]] is additionally possible), without sacrificing the [[Graphics processing unit|processor]] cycles required to create the same effect with geometry calculations.<ref>Dynamic Parallax Occlusion Mapping with Approximate Soft Shadows - Tatarchuk

Parallax occlusion mapping was first published in 2004 by Zoe Brawley and Natalya Tatarchuk in ShaderX3.<ref name="Original Document"/> Natalya Tatarchuk conducted presentations of the technology at [[SIGGRAPH]] in 2005.<ref>http://www.siggraph.org/s2005/main.php?p=sketches&s=sketches3&f=conference</ref> It was used in [[ATI Technologies|ATI]]'s 'Toy Shop Demo' to showcase the [[Radeon X1800]]'s Ultra-Threaded SM 3.0 technology.<ref>http://www.trustedreviews.com/graphics/review/2005/10/05/ATI-Radeon-X1800-Preview/p2</ref> It is used in video games and rendering engines such as [[Unigine]],<ref>http://unigine.com/products/unigine/</ref> [[CryEngine 2]],<ref>{{cite web |url=http://www.cryengine2.com/index.php?pnr=1&conid=2 |title=Archived copy |accessdate=2009-12-10 |deadurl=yes |archiveurl=https://web.archive.org/web/20091130224928/http://www.cryengine2.com/index.php?pnr=1&conid=2 |archivedate=2009-11-30 |df= }}</ref> and [[CryEngine 3]].<ref>{{cite web |url=http://mycryengine.com/index.php?conid=2 |title=Archived copy |accessdate=2009-12-10 |deadurl=yes |archiveurl=https://web.archive.org/web/20091017063147/http://www.mycryengine.com/index.php?conid=2 |archivedate=2009-10-17 |df= }}</ref> It has also been used to create [[Stereoscopy|stereoscopic]] images from single images.<ref>http://www.scalari.net/2008/04/22/generating-stereoscopic-images-with-parallax-occlusion-mapping/</ref>
