'''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">{{Cite book |last=Engel |first=Wolfgang F. |url=https://books.google.com/books?id=DgMSb_10l7IC&dq=parallax+occlusion&pg=PA135 |title=ShaderX3: Advanced Rendering with DirectX and OpenGL |date=2005 |publisher=Charles River Media |isbn=978-1-58450-357-6 |language=en}}</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>
