Relief mapping (computer graphics)

<p>In <a href="/facts/Computer_graphics/lapBE8wv">computer graphics</a>, relief mapping is a <a href="/facts/Texture_mapping/9gDTsuXN">texture mapping</a> technique first introduced in 2000 used to render the surface details of three-dimensional objects accurately and efficiently. It can produce accurate depictions of <a href="/facts/Hidden_surface_determination/hk9dqmDE">self-occlusion</a>, <a href="/facts/Self-shadowing/IkDoPM4K">self-shadowing</a>, and parallax. It is a form of short-distance <a href="/facts/Ray_tracing_(graphics)/n6qpap2q">ray tracing</a> done in a <a href="/facts/Pixel_shader/qfhkKFwA">pixel shader</a>. Relief mapping is highly comparable in both function and approach to another displacement texture mapping technique, <a href="/facts/Parallax_occlusion_mapping/GPdC10h2">Parallax occlusion mapping</a>, considering that they both rely on ray tracing, though the two are not to be confused with each other, as parallax occlusion mapping uses reverse heightmap tracing.
