'''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. 2005. 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
